If you are extremely rich and you can just gamble up to your heart's content, does the novelty of winning wear off? Like would you get tired of gambling since there's really not much risks because you can gamble with any amount and still receive little to no consequences?
I believe irresponsible gambling practice by the rich will turn down their bankroll leaving them bankrupt afterwards, so placing the fact that you're rich and can outrun some certainty relating to gambling, it's only going to result in you loosing all what you've worked hard for so better still applying wisdom and managing your bankroll matters regardless.
