If the status of a rich gambler was originally that of a businessman, he would know that gambling is not the only way to seek wealth, so he knows that it is just for fun, so rich gamblers rarely make mistakes and end up addicted to gambling, we often find poor gamblers because they just want to try their luck to get rich quickly without any process, so that's what we have seen so far, no rich gambler has gone bankrupt because of gambling, of course he knows how to manage his money.
Especially in gambling, of course he will gamble with the money he is ready to lose so they don't mind that, if a rich person goes bankrupt because of gambling, he is not a businessman who started from zero and is rich, but is rich because of his parents' inheritance, usually gamblers who are not clever in business he will try to gamble to double his wealth and finally run out and go bankrupt, the gambler cannot be called a rich gambler because he is rich only from inheritance from his parents, there are no rich gamblers who often do business let alone go bankrupt because of gambling. They are definitely not stupid like poor gamblers who keep forcing themselves to gamble because they want to get rich quickly.
Addiction have nothing to do with a skill of handling money or stupidity. It's a chemical process, that some people are more susceptible to. Getting addicted is not a choice, and often happens without our noticing it, like having fun in a warm water, but realizing slowly we are a crab that slowly gets boiled.
History is full of rich people that ended up dead and poor and forgotten because of untreated addiction and other mental disorders. And rich people gettiing addicted to gambling is quite common, because money is something they are familiar with, so, change to win lots of more or lose it raises excitement easily. And their brains just want it more. It's a chemical thing and brain wiring. Not a matter of being responsible or sensible around money. If it's not a casino they are gambling on, it might be day trading or markets in general.
And from my experience, there's a change that these broke ex rich people won't get bailed out by their friends, as they fake not having problems until the end, when everything is either lost or gained back. Poorness is just too shameful for them so they might not even tell their partners or close friends that they have problems.
And something that happened at least one associate of mine, that he got rejected by his old circle of friends, who avoid him after getting broke. Poorness to rich people is sometimes a reminder it can happen to them as well, so my guess is that they will avoid it like a disease, because they assosiate it to wrong ideology, wrong crowd and weakness. That was sad to watch.
