~ I know as time passes people gets more knowledge and gain skills in gambling to become an expert it’s important to spend time with it as much as possible and if you are satisfied with your earning from gambling then you can choose it as a profession.
If you are intended to spend a lot of time on learning a profession, please choose anything but gambling as the subject of your study. Indeed, you can succeed in many fields devoting your time and efforts to the process of learning, but gambling is probably the last thing you should consider as your potential profession. I can't imagine where else so many things depend on luck rather than on your skills.
Learn a decent profession, make good money with it, and gamble at your leisure, when it suits you, and maybe, even knowing little about a game, you will win big one day, because luck is the main factor in gambling, not your knowledge.
