There are more white dwarfs than black holes in the universe. White dwarfs are the end stage of low to medium mass stars, while black holes are formed from the remnants of massive stars. Since low to medium mass stars are more common than massive stars, there are more white dwarfs in the universe.
White dwarfs, because all stars end there life cycle's but not all stars collapse into black holes. Only the super giants can collapse into a black hole so since there are more medium and smaller stars than there are super giants then it stands to reason that there are more white dwarfs in the universe than black holes.

What is more common in our galaxy white dwarfs or stellar mass black holes?
There are more white dwarfs. Only the most massive stars can form black holes. White dwarfs form from low to medium mass stars, which far outnumber the supermassive ones.
Why have black dwarfs not been seen?
It is estimated that it would take trillions of years for a white dwarf to cool to a black dwarf, which is more than the current age of universe. So black dwarfs do not exist yet.
Are black dwarfs hot?
Black dwarfs by their name are the opposite of hot. A black dwarf becomes a black dwarf when all residual heat has escaped into space. They will be as cold as space itself. See related question. If this is not an astronomy question but one of "another sexual" nature then I suggest re posting with more precise details in the question.
What is the fundamental quality of star that indicates its ultimate fate?
The mass of a star is the fundamental quality that indicates its ultimate fate. A star's mass determines whether it will end its life as a white dwarf, neutron star, or black hole. More massive stars are likely to undergo supernova explosions and collapse into neutron stars or black holes, while lower-mass stars will evolve into white dwarfs.
Why do some stars die out as neutron stars while others die out as black holes and white dwarfs?
The fate of a star depends on its mass. Stars with lower mass, like our sun, end their lives as white dwarfs. Stars with higher mass will end their lives as neutron stars or black holes depending on their mass. Neutron stars form from the remnants of massive stars that undergo supernova explosions, while black holes form when the core of a massive star collapses under its own gravity.

Do you think there are more white dwarfs or more black holes in the universe?
More white dwarves. Most stars will become white dwarves at the end of their lifetime. On a "select few" will become black holes - the most massive stars.
What are remnants of low mass stars?
Remnants of low mass stars include white dwarfs, neutron stars, and black holes, depending on the mass of the original star. White dwarfs are remnants of stars similar in mass to our Sun, while neutron stars and black holes are remnants of more massive stars. These remnants are formed after the star exhausts its nuclear fuel and undergoes a supernova explosion.
Why have black dwarfs not been seen?
It is estimated that it would take trillions of years for a white dwarf to cool to a black dwarf, which is more than the current age of universe. So black dwarfs do not exist yet.
Why is the white dwarfs white?
They are called white dwarfs because when they form, although not replenishing their energy supply any more, they are still hot enough to shine. Overt time (a long time) however, they will cool down and become 'black dwarfs' which no longer emit light in visible wavelengths.
What are Three things stars turn into when they die?
Stars can turn into white dwarfs, neutron stars, or black holes when they die, depending on their initial mass. White dwarfs are the remnants of stars with low to medium mass, neutron stars are formed from more massive stars, and black holes are the result of the most massive stars collapsing under their own gravity.
How far is the earth to the black dwarf star?
There are not black dwarfs. It would take trillions of years for a white dwarf to cool to a black dwarf, which is more than the current age of the universe.

What stars turn into white dwarfs?
Sometimes if the conditions are just right a huge diamond! (the final stage of nucleosynthesis of stars that are not more massive is carbon Theoretically, they get dimmer and dimmer until they become "black dwarfs".
Are white dwarfs older than the sun?
Some white dwarfs are older than the sun, and some are not. More massive red dwarfs form from stars larger than the sun, which do not last as long.
What happens as stars die?
Exactly what happens depends on the mass of the star. Low mass stars first expand into giants, then shrink to white dwarfs. Stars with a little more mass than the Sun end up as neutron stars; stars with considerably more mass with the sun end up as black holes.
Are giants hotter than white dwarfs?
No, white dwarfs are much hotter than giants. Giants are stars in the later stages of their evolution, while white dwarfs are the remnants of dead stars that have exhausted their nuclear fuel. White dwarfs can have surface temperatures in the tens of thousands of degrees Kelvin, while giants have lower surface temperatures.
