Even though rich people have enough money it doesn't mean they will be fine, it's true what you said, greed doesn't respect anyone, those who can't control themselves will certainly go in the same direction, namely addiction and losing a lot of money. Maybe this is more about what each individual's approach is like, because if they are very close to gambling then it is possible that they could become addicted to gambling. What's more, it seems like everyone has greed for money. But the point is, don't take risky actions, especially without considering it first, because addiction and other bad impacts don't matter whether you are rich or poor.
That's the point, the difference in terms of getting engage and unable to control is just the same, greed inside us mostly push us to keep playing and keep trying our luck, if things turns to an out of hands gambling participation chances to lose a lot is possible, even how rich you are the risk that you may lose everything is just the same with poor gambler, limitation is needed as if you forget about it then you may suffer the consequences.
For rich people, maybe they can ignore their losses because they still have enough money to continue their daily lives, while for poor people they definitely gamble with the aim of winning, which is a monetary gain that can help with their financial problems. where they risk the money they have to double it in gambling, it is clear that they are full of hope in gambling so that a miracle will happen by getting a win, but of course they will most likely only experience defeat and experience worse conditions.
It's on the side where rich gambler is capable to control and limit their budget, knowing that they can easily recover that using other source of financial income, unlike with poor gambler, once they lose it affects their entire financial status.
