For me main danger of becoming a professional gambler is an unpredictable future. If I work on a regular job, or I am an employer, I have risks, but my far future and old age are protected by taxes and pension. In some way, I get support from government. Becoming a professional gambler for me is risking a life. I risk during gambling, additionally I risk with my future and additionally I risk if I have a family. For me this is too much risk in exchange for only a chance of success.
You have a point on that. But that's if a gambler will only focus on being a professional gambler. I bet there are those who also have a day job while also gambling in their free time.
I agree that there's no future in doing it mainly. There's no pension, but there are taxes. There's no income tax retur,n but gambling is still taxable. Then, you will have to save a lot of money so that you will have something in case you retire from doing it. I mean, there's always a time that our mental state will deteriorate and I don't think it's healthy to still gamble at that point or we are just going to lose more without thinking clear.
