But if a player can afford to lose, for example, $ 10 million, then it is obvious that during the game he will win one million at least once, right? I think this is quite easy to achieve and it is a large sum. But I am 100% sure that after such a win, this player continues to play and this is explained by the dependence on the game process.
One great example is Floyd Mayweather, he is known to be a high stake gambler especially in sports, and until now we haven't heard a news that he is already bankrupt, so that says, if one has the control regardless of the amount involved, he will be able to enjoy gambling.
I think this is not the best example since he has huge incomes in the past and I think in the present. He has a name and even if he completely loses his money, he can more or less easily recover a significant amount from the lost one. Many organizers of events, interviews and other will easily pay him a good sum for the very fact of his presence.
