First thing first, I doubt if there's anything or anyone known to be a professional gambler and I'll really want to know from the person's perspective on what it takes to become a professional gambler.nevertheless gambling is meant to be enjoyed not a medium of doubling one's income and along the line while doing it results to some damaging benefits which are what you listed. So if I'm to spot one dangers,it poses high addiction rate of individuals
A professional gambler is someone who has complete control over the time, money, and energy they spend gambling. So they have the power to control their emotions to avoid becoming addicted. I think external conditions such as crime would be another motive for harm to be seen. It may be due to gambling results or competition in professional gambling. But the current condition is that people who tend to have a lot of addiction news are beginners who start learning to gamble to make money.
