Whatever it is in gambling it is difficult to guess whether their gambling games will succeed with profits or not, because if we have capital of $100 for example it wants to be 10x in gambling then it's not possible unless luck siding with you in gambling games is difficult to win even often losing in the middle of the road with the emotions we face is therefore consistent with gambling I think is useless.
It is not even just luck, there is mathematics involved with gambling, there is a house edge and I think that is a reason enough that there is a guarantee you can't make a living out of gambling. Once again I am not saying you won't win, you can win, but you can't make a living out of it when you are playing against the house. This is not poker or anything, this is against the house which has an edge against you.
I don't agree 100% in this statement, I known lots of people who earn their living in a Casino. It is a matter of right strategy in every session I guess. I have talked to one of them and told me that it is a matter of discipline and planning when to quit. Though this person said that he does not win all the time but he is sure that he is raking profit in his career as a gambler.
You can win and lose same number of times which will make you lose all your money, so if you win once and lose once forever, you will lose money that way. At the end of the day gambling was made for fun, you gotta just play and have fun and try to entertain yourself, if you can't do that and focus only the money part of the deal, you are not going to get anything in return.
Not only that gambling is made for fun, it is also created for socialization and a meeting place for those who have a higher status in life.
