I'm not rich from gambling but you can become rich by gambling with a lot of luck of course. I think if you have this luck you should never gamble anymore because you can only lose it again in my eyes..
There are only chances in getting a profit in gambling because risk will always be your enemy in it, and I think some people have won because of chances and there ain't more people that are getting a lot of winning even if he is feeling lucky but there are gambling methods that have large amount of chances of winning and that is sports betting, and poker!
