I think it all depends on the person. I can say for myself, no matter where I work and how much I earn, and no matter how much I win, I always start saving money first. That's why I always have enough money. This is called financial literacy. It's not enough to be able to win a lot or earn a lot, you also need to be able to manage money correctly. I can say the same about a big win, of course, after a big win, a person's internal state changes, but one person will fall into depression, as you wrote, and another, on the contrary, will have an incentive and inspiration to continue winning even more and constantly work on himself and his game.
