Rich or poor cannot be used as a benchmark for who should take greater risks in gambling, because each individual has a different financial situation which in turn the perspective on money will also be different, or what I mean is that simply for a poor person $100 is very large but for a rich person it is a small amount and the point is that rich or poor they still have to take risks that they are able to take responsibility for such as putting small amounts of money on gambling.
We must understand that gambling is nothing more than a probability activity that only provides two possibilities, namely winning or losing, and the name of the possibility can never be known about certainty, so it means that no matter how much you put money in gambling with the aim of getting a much bigger win then it will not affect the results at the end of the session, still in the end if you are unlucky then you will lose or vice versa. Therefore, putting a lot of limits is always recommended because of the possible risks that you can never avoid completely and also because of this possible risk we are advised to make gambling a place to have fun without putting any expectations on winning.
I agree with you, that makes sense too. because every person has a different financial situation, and in my opinion this also depends on the gambler's approach to gambling, because even though their finances are bad, if they have a strong approach to gambling because they are chronically addicted then they will gamble even though They don't have good finances, but if they are seriously addicted then it is very likely that they will force themselves to continue gambling by doing anything that can make money for gambling.
That's true, indeed gambling will only end with two possibilities, namely winning or losing, but in my opinion what will happen more often is that the end of gambling is losing. We have to be aware of that, because it's true what you said is that the possibility cannot be guaranteed in the end, but with gambling the only thing that can be guaranteed is defeat.
