Nobody is fortunate that it continues forever. I agree with you. Luck is only part of the many factors that influence it. So don't use luck as the main factor in gambling because in the end you will lose. Call it also like trading activities, maybe people will be lucky, but fundamental technical analysis is absolutely necessary.
I've read that if you gamble you need expertise. Read a lot and of course practice is one way to train yourself. But your mental skills also really need to be mastered, remember not to be greedy. Because this is a very difficult thing for people to have.
