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?

I have always win less, no reason to lie but I get curious when I see gambling related posts online about people pointing to some gamblers calling them professional and the only vital point of this all is because they won many times in their own way.

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.
