A classic question behind everything you tell in this thread. believe me, we have discussed here many times regarding what you are asking. but, let's discuss. what you ask, the answer will be relative depending on each person. in fact, we often hear stories of successful gamblers regardless of whether they are true or not. but at the very least, if you want to be a professional gambler, you should qualify for it. you must have broad insight, very high knowledge, also, skills. but not for all types of gambling, at least for types like poker or sports betting.
on the other hand, if what you are passionate about is casino games. it's hard, because you bet with pure luck. So what are you asking, the answer is in you. because, for me personally. gambling is a place for us to have fun, sacrificing a little money in exchange for getting some decent entertainment.
