Crazy it is and those that have been winning great but then are bad with risk management, that money that they've got will be gone in the wind quickly.
They think that luck comes at most times where in fact that it's not. And that's why every profit that someone makes from the bets that they do should be taken care of properly.
There is a lot of empirical evidence this is the case, as even those that win a big jackpot or the lottery soon enough find themselves facing all kinds of financial trouble despite all of the money they got, and it is not surprising this is the case, since they do not know the amount of effort that it would have taken to earn that money by working hard, so they spend that money thinking that it is never going to run out, until one day it does and they are left with a lot of debts they cannot pay.
That's true, they've taken that vast money easily so they're going to spend it carelessly easily. But if someone values their winnings and they understand how hard it is to earn a lot of money based on the winnings that they've got, they will for sure going to protect it with all their might and will start to spend wisely so that it won't be gone too soon. Many of these type of gamblers really are ashamed of themselves when they've taken the spotlight but then later on losses almost everything that they've won.
