A lot of people here gamble to become rich, but some do it for fun.
The question is, if you wake up tomorrow with 50 million dollars, would you still gamble for fun, or would you forget about gambling and do other stuff? Personally I think I would still gamble. I do it now, and I know I realistically will never get rich off gambling, because I barely do it and I don't risk much money, just for fun sometimes, to test my luck.
So if I had a lot of money, I would do bigger gambles, but they would still enter in the "for fun" amount (for the new 50 million standard). For example, gambling 1K a month would be irrelevant, and winning with a 1K bet can give you big rewards if you are lucky. It would still be fun, in fact more fun, and it would be as non risky as it is now, in terms of going financially bankrupt.
In real life those rich people or artist spend their money in gambling in casino. Knowing that they have lots of money that whether they lose or win it will not really that matters . That's why staying rich is hard to do they will only realize it once they lose everything so for me of ever I got rich I'd probably stop gambling and tried to do businesses or invest in stocks.
