~ and this is because in their minds gambling will go from a hobby which they may enjoy once in a while, to a way to make money in a consistent way, and this is a very problematic change on their beliefs, as there is no way for someone like them to actually achieve their goals, so very soon they will lose all the money they won and more.
This is exactly why they are in danger in my opinion. While having little to no experience in the field they got lucky and win a lot, and many of them start thinking that can continue that way and win even more, and that's a big mistake to think like that, but unfortunately this is what happens to a lot of such people.
But it's true, I also when I've tasted victory feel that I have great luck and think it's quite easy to do without spending critical thinking and sweat to get money in gambling, when before it was just playing for entertainment but instead it became a habit that lost a lot of money because of addiction to the benefits, past tours.
