Well that's true as most people with good financial management skills don't tend to gamble. They see it as unnecessary risk, and reward ratio is too low. But i personally know some people with good financial management skills that just love gambling so much that they want to take the risk. They are just good at keeping seperate balances for it so that they won't be blowing their budget. Not every gambler gets so addicted that they want to compromise their budget. Those are just the addicts you hear about. Lots of people with addiction that are battling against it every day can manage their addiction. And i am not at all downplaying others problem with gambling. I am just saying that it's definitely not for everyone.
I think not all, not all people who wants to gamble has the reason for it to gain more. Some of those people who knows how to manage their money also gamble because they just want to have fun, most of the people I know prefer traditional ones because they want to see their amigos and amigas in gambling. We can't deny the fact that those people who fall into addiction are the ones who doesn't have a lot of money or those who believe that gamble will be their only want to get rich.
You are absolutely correct, it is pretty difficult to find really wealthy men who are so glued or addicted to gambling, if there be any, then there is also the possibility that such person has been addicted to gambling before getting rich through it or other means.
I have a guy in my neighborhood who was and still is really into sports betting, wouldn't call him addicted yet but a day does not pass without him putting up some bets, he got really rich from his investment in crypto currency back in 2020, and till now, many still think and believe he made his money from gambling, and see no reason to advice him to stop or reduce the rate at which he throws money at sports betting.
