No, cactus plants don't branch necessarily every 50 years. In fact, not all cactus plants branch. Not all of those that do branch have a life expectancy of 50 years. Those that do live 50 years and more can't count on regular intervals between branching. For example, environmental factors, such as extended drought, get in the way of any predictable pattern with the giant saguaro cactus [Carnegiea gigantea]. The saguaro has a life expectancy of 150+ years. It first branches at 40+ years. But subsequent branches can't be counted on to appear every 40-50 years. The desert can be counted on for predictably high levels of heat and light. But it can't be counted on for consistently adequate or regularly occurring amounts of moisture.
No, it may take over 100 years for the cactus to sprout its first arms.
A saguaro cactus can live up to 250 years.
There were many plants 400 million years ago. Many of them were very large compared to modern plants. There were trees, cactus, and ferns, to name a few.
It depends upon the particular cactus. For example, the old man cactus [Cephalocereus senilis] reaches a mature height of 50 feet/15 meters. It may mature to an age of around 200 years. It's slow growing. So it doesn't flower the first 20 years of its existence.
A cactus tends to grow better in the ground when the outdoor environment most resembles its native habitat. But cactus plants are adaptable survivors and handle being in a container. A container becomes a problem when the soil isn't changed every couple of years, when the size is way too big for the plant, and when drainage holds either not enough or too much moisture.

The Saguaro cactus [Carnegiea gigantea] takes about 40 years before it forms its first branch. That also is the length of the wait before the plant's first buds. As a result, the plant's hallmark huge flower and tasty fruit likewise don't show up until the giant cactus is about one-fifth of the way through its 200 year life expectancy.

A cactus has branches to increase its chances of reproducing. Flowers grow on the tops of cactus parts. That's where the growth buds are located. For example, the giant saguaro cactus [Carnegiea gigantea] matures to a height of 40 feet/12 meters. At around the age of 40+ years, it begins to branch. It's at that time, and on the branch and stem tops, that flowers may appear. Pollinated flowers produce fruit, which contains seeds. The seeds drop naturally to the ground, where they germinate. Or they're eliminated by the digestive tracts of predators. In this case, the seed tends to be spread over a far wider area than that in which the seed producing cactus is located.In the case of low growing plants, such as the octopus cactus [Stenocereus alamosensis], the branches give the plant yet another means of reproducing. The branches have the possibility of rooting in the soil over which they're bent. This makes it possible for the octopus cactus to take over the space in which it already is located. Combined with seed dispersal, this ensures the survival of the species within its particular niche of the desert environment, and in other niches.Additionally, branching arms the balance to the cactus plant. They also increase the amount of internal storage space for water and watery products and solutions.
