Some after loosing a certain amount in the process of gambling they just put a stop to it and never gambles again because of the fear that they might loose even more if they continue gambling in that way.
Though hard luck is seasonal and after a particular period of time, someone that finds it deficult win might eventually win again, if you're able to at the point You're loosing put a complete stop to your gambling practice, it's what suggest that becoming addicted is actually far from you.
It is very lucky in my opinion for people who can immediately stop when they have experienced one defeat with gambling, I myself once found it difficult to stop gambling when I first learned about gambling, because I had tasted victory so there was an element where I was gambling to pursue victory.
A person who has difficulty winning I think even occasionally they get a win and that some of it is successfully withdrawn and some of it runs out again because of the pursuit of a bigger win.
I'm sure this happened to you at the very beginning when you started playing. All novice players go through this, and I think it's absolutely normal, because we are guided by our emotions at first, and only later do we realize that these were impulsive decisions. Later, when a player has gained experience and understands what the consequences might be, they don't make the same mistakes they made at the very beginning of their journey, trying to win back what they lost and not driving themselves into big losses.
