If we follow and pay close attention to how the rich people play or bet, it will be difficult to understand because they bet using their logic based on a large enough capital that no matter how they do it they will continue to win.
we can assume he is a rich man from the amount of betting funds but from the assessment of the odds that he does not accept losing the funds because his predictions are wrong, he increases the betting funds because he has predicted that he has a great chance to win even though the winning amount is very low compared to the betting capital. However, this type of gambler is very rare, even though gamblers are rich they still consider the risks of each bet and are not greedy to get profits with risky bets.
I used to have a friend of that love betting on football matches, and in most cases he is constantly on the look out for smaller odds and once he can see the lowest of them all, he will place his bet on that particular games because of the small odds and now stake big amount this kind of gambling habit is popular among.
-big money bag holders, who are scared and lazy to do analyses and instead of calculating and connecting the odds they just choose the small odd thinking it to be a sure odds.
