The mass will always be a larger or equal number to the atomic number. The only way it could even be equal is with Hydrogen, where there is only one proton to affect the mass. That is because the Atomic Mass is the combination of all protons and neutrons in that atom. Also, it is often written underneath the atomic symbol. In more advanced chemistry classes, the atomic number is a long string of digits after the decimal. This is because that is the average atomic mass between all of the known ions of that element
Here is an example using Carbon, as it is often shown, with the average atomic mass:

The mass number is typically located at the top left of the element's symbol on the Periodic Table. It represents the total number of protons and neutrons in the nucleus of the atom.

Why was mendeleev's periodic table valid at all?
Mendeleev's periodic table was valid because he arranged elements based on increasing atomic weight and grouped elements with similar properties together. His periodic table had gaps for undiscovered elements and predicted the properties of these missing elements. Additionally, Mendeleev left room for the table to be updated and adjusted as new elements were discovered.
