Regular gambler = has long-term losses
Professional Gambler = has long-term losses
In both cases there is no big difference, so much so that the guys who consider themselves sports bettors keep creating YouTube and Telegram channels and selling courses as a source of income and do not show proof that they are making constant profits from gambling. In my opinion, people should not gamble with the intention of making long-term profits because they will fail. I've seen many sports bettors who consider themselves professional bettors but who never post their supposed profits
Totally depends specially that this is something that we do talk about professional gamblers on which we can say that this pertains about those sports bettors and those who play poker or simply with those strategic games on which some people could be able to apply. Yes, both does require luck all the time but there's always that fine line in regarding their differences on which it will be something significant on how gambling being handled or being that dealing on with. Luck factor is the main reason of winning but there are those times or moments that analysis and experience will be that significant.
Those qualities of gamblers above in OP are indeed precise but come to think that a Regular gambler could become a professional at the moment that he do continue out on what he's been dealing on with.
Sooner or later, he would be able to develop out those qualities as he gained up experience and able to sustain out. We cant say that they will be that still on losers side because you wont be sustaining out
if you have that very deep loses and seeing into a point that its pretty useless on dealing up with betting or something you've been dealing into.
