I remember years ago when I was in school, it might of been high school, basically a year or two right before we would become legal drinking and gambling age, there was a seminar about the dangers of gambling, drinking, drugs, etc.
Anyway what I remember very clearly when they talked about gambling was that. If someone goes to a casino and loses a bunch of money, they will go away and most likely won't come back. The scenario where people become addicted are those that go to a casino for the first time and they win, they basically realise its easy money and they will become addicted to it.
I guess you call this beginners luck, they realise its easy making money in a casino and they will keep doing it. Eventually they lose their wins, plus any other money new money they put towards winning it back. So its the opposite of what the OP described.
For what I have observed this is the way it works, the people that I have seen getting terrible results on their first gambling experience will hardly gamble ever again, as memories of that session will come back every time they think about gambling again.
But those that obtain positive results, learn that gambling could be a way for them to earn money and do so while obtaining some fun, and such thoughts are often the basis of a behavior which could later get out of control.
This is what I know, in the case of users or people who are just getting involved in gambling for the first time, won't they be given a winning percentage in terms of gambling, even though it counts and provides a sense of comfort in gambling, if the user has enjoyed gambling, that's where the losses start because of the site. It has created a high curiosity effect without us realizing it when gambling, that's why the target currently targeted by gambling is new users, the rest are just people who fill the void, after all, if gambling results in continuous losses, it is impossible, of course the winning percentage will be high. given that the gambling site definitely exists, the gambling site will realize that if they only provide a small winning percentage, people will definitely leave the site, correct me if I am wrong in my interpretation..
