For me, I will say that the rich have a means of income that generate money for them, they already have something that gives them money weekly or monthly, so they only gamble wisely, some don't even believe in gambling, most of them can only invest in Bitcoin or any other investment Asset not like gambling, majority of gambling addict are people from the lower level, because they don't believe in hard work,so they prefer gambling since it's not stressful, so for me I think the lower level gamble more than the rich.
