Is been responsible with gambling all it takes to be a professional gambler or someone needs to win in the process many times already to be considered a professional gambler?
This is just like asking a taxi driver that because they drive does it make them a Formula 1 driver? That you Gamble responsibly does not automatically qualify you to be a professional in gambling. I do not know how else to explain this but I hope this point is clear.
What is a been qualified as a professional gambler in your own world? The winning part or the responsible part of trying to avoid addiction is all.
A professional gambler in my estimation is one who is like a pundit. He gambles and finds a way to make money from other gambling related activities.
