Since you gamble for profits there will be no need for hou go gamble anymore because you are already wealthy. Bit people who gamble for fun like myself will continue gambling when I am wealthy. That's the time that I will enjoy gambling the more, because I wouldn't have any emotional truama or sleepless nights after losing big.
The only exception to that is if the person in question is already addicted to gambling. No matter how much money you've got, if you're addicted to gambling, it'll still be difficult to control your gambling and it might only take some time to burn out your wealth on gambling. Even with an infinite figure in your bank, you still need to prioritize responsible gambling because without it, it'll only take time before you start getting financial strains from gambling.
The cycle of money comes in and goes out. The amount of income depends on how hard we work, and expenses also depend on how extravagant we spend. It could also be said that no matter how much income we have, if our expenses are much greater, it will eventually run out. So I quite agree with your opinion that no matter how much money we have, if we are a chronically addicted gambler, we will eventually go bankrupt. There are many cases of businessmen going bankrupt and losing all their wealth due to gambling addiction.
This means that management and limits are still something that needs to be applied no matter how much money we have. But perhaps what differentiates the rich from the poor in a scenario of decline is simply time. The rich need a relatively long time to spend it all.
