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
The truth is, you can overcome the house edge
Although it is unlikely you will be able to make a living out of it, for a "proof of concept" it will suffice. The idea in itself is pretty simple. A casino is as vulnerable to randomness as a regular user (minus the house edge), and if you are able to take advantage of this simple fact, you can beat the house edge in a statistically significant way. It is kind of loophole which has implications and applications well beyond gambling. That's basically one of the reasons why gambling and games of chance in particular are important for learning the ropes of life (read, this knowledge can be transferred to other areas)
