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!
I would figure that sports betting is a whole lot more safer than betting with odds with poker.
You might win more with poker + it is more fun, in reality it isn't really worth the stress.
Actually sports betting is much better and people who got rich are also with gambling. There are many reasons for this, one is as obvious as it can be because we can use our knowledge and previous records of the team.
Others can be like sometimes we can martingale and with sports I think we wont loose 10 times in a row lol
