That is so true.
There might be a time that they actually won but that doesn't cover the fact that they are also gambling for a long period of time and that also means that they are experiencing losses in that long run. Obviously, they have other sources of income or profit other than gambling because for sure they know how cruel gambling is.
There is no different thing between a professional gambler or ordinary gambler, they will have an equal opportunity to win or lose. Because there is no spesific strategy to make win or lose, they just depend on their luck for sure. I am someone who has always had the understanding that no one can live as a gambler, regardless of whether he is rich or not. Gambling cannot be used as a source of income, you can imagine how a person can live by gambling while he has to spend every day to live while he does not ensure that every time he gambles he gets money, psychologically this is something that can be accepted.
Then the term shouldn't exist, right?
Obviously, there is a huge difference from an ordinary gambler to a professional gambler. Of course in terms of luck, either an ordinary or a professional is in the same spot but in terms of creating these opportunities or plays make them higher to those ordinary gamblers. They have built this experience and knowledge that made them a professional.
