So in my opinion, don't try to finance gamblers because it won't work. most likely like that.
After all, why do we have to pay for other people when we still need money to gamble with ourselves, play at our own risk, look for our own entertainment in gambling without having to interfere with other people or if someone professional asks or borrows money, it's best not to give it. Because of that, there is definitely a risk of losing too, it's best to just focus on playing yourself because it's better than paying for someone else.
So I think it's better to do it yourself whether you come just for fun or even for income, both are recommended to do it yourself, and if you pay someone else I think it's like you're relying on someone else's luck which is basically always unknowable about how lucky that person will be. If you do that then I honestly don't understand what you have in mind haha.
