Well, it is a fact that things when dealing with addiction are delicate, it is true, addiction is better treated when it is not severe, but in cases where it is really advanced something has to be done, because the more advanced it is, things get worse as you play and if you have little money or little left, things get much more complicated.
Addiction can start after winning or in a losing streak, that is why we must be aware at the time of playing how much we should spend.
An addict must have a strong intention and determination to stop their addiction, because many of them think that it makes them in a difficult situation but they can't get out of that zone so they continue it. Well, I myself experienced it where I spent a lot of money in one night, making me realize that I was addicted to gambling, but with that incident I finally realized and limited the gambling that I did, it was because of the strong intention and determination in myself. It is true what you said, gambling addiction can occur when we experience defeat or victory, the exact thing is more dependent on ourselves who have a mindset like what in viewing gambling.
