I think it all depends on our economic situation, because a poor person can play and have fun, not with large amounts of money but with what he can afford to lose, even if it means playing only with 5usd but he will enjoy those moments to the fullest, for me nothing else is needed but to know what we are getting into and how we should bet according to our situation, if we are clear about that there is no need to be rich to play in a casino.
If it is only once in a while and you bet with money that you can afford to lose, it may be okay. However, it would be better if when we are in a difficult economic condition, instead of using that little money to gamble or place bets, it is better for you to use the money to meet your needs or at least buy delicious and tasty food for your family, and enjoy it together. Because sometimes small things like that can make them happy, and when you see their warm smiles you are happy too. That is better than you spending money on gambling.
When experiencing difficult financial conditions, it does not mean that you should not gamble, but being self-aware is very important.
