do not believe in anything called professional gamblers. I see it has something that can be deceiving because there are rich people that can go broke at anything. Gambling can be one of the reasons if you solely depend on it.
Even on the gambling site terms of service, it is highly advised that people should gamble just for fun.
Is there really anyone called a professional gambler, no i don't think so but if there is, then it's just sarcasm or myth. No one is actually a professional when it comes to gamble, though we find some people calling themselves professional gamblers because they managed to pull some series of win for a while. We all also at some points in our lives experience series of wins but as luck would have it, we cannot always depend on it because gamble is filled with uncertainties.
