I dont unse your theory dude...and make sure first of all gambling is not for making money..it is for fun or entertainment but the one who plays it for making ends up in loosing it..so you must be ware dude on why you doing gambling
If you play for fun it is fine as you will always be in your limits and not will keep on playing daily to make money. So it is a good idea to play for fun, but for people who want to make money through gambling is the high risk as losing the money is very high.
So you believe that the fun seekers are out of the danger zone because they are not greedy. Well, I think it is not that simple or true. Gambling is an addictive game and there are people who waste time and money for the sake of pleasure and relief only. It is just that money seekers are considered worse and more vulnerable to pain due to their greed. Well, that is also true to some extent but anyone can grow addict.
