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?
No. There are so many better ways to spend your money, you can donate for charity and save some lives, you can fund some researches, you can invest this money or start your own business. There are countless possibilities to make good for yourself or other individuals or society as a whole. But if spending big money on gambling is essentially just giving them to casino owners. So I would only gamble with small amounts and preferably in PvP games like Poker.
