This is a very fine line between gambling and addiction for any player, no matter how pro-gamer he is, but that’s why a professional is called such that he can control it. I am sure that there are professionals who, after many years of playing, broke down and fell into the abyss. But if he starts with low limits, then he will be able to rise again if the fall was not fatal and did not cause him severe moral suffering turning into chronic depression.
Indeed, it is a fine line, and it is often difficult to distinguish it. But with our experience, we can know and differentiate it. Yes, I agree with you that there are professional players who end up losing a lot and despair because they cannot control themselves well while they are gambling. They forget that gambling has many temptations, so they seem to underestimate gambling and say they are used to dealing with it. But from underestimating them, they will start to encounter problem after problem, which, in the end, they cannot handle and makes them start to lose control of themselves in gambling. He would feel like he had hit rock bottom again and might not be able to get up again if he didn't quickly realize that he had made a mistake. By realizing his mistakes and the desire to correct his mistakes, he can get back up and start correcting the mistakes he has made.
I remembered a moment from the movie Molly's Game. There, one day an old and calm professional player came to Molly Bloom’s club and decided to play poker. There were other players sitting at the table who played well, but there was one who played terribly, he played with different cards and placed different bets. So this old pro started losing hand after hand to this amateur. This happened all the time, the other players even started laughing at this situation. All these reasons caused his tilt and he lost everything completely. Then he borrowed more money and lost it.
This situation showed how a professional player sinks to the bottom. I liked how it was shown in the film, I think in reality there were many such situations. I would call this a guide for professional players. If they feel that they are sinking to the bottom, they should remember this part of the film, it will probably stop them.
