This is the same with "gambling must only be for fun and never for serious matters". Must agree.
People should really treat gambling that way.
I mean gambling is not something that people should be serious unless you have the ability or skill to be a professional. It doesn't mean that you can win games by yourself, which means that you can also be a professional.
but even profesional gamblers does not take it seriously when they step up on the gambling arena playing or competing with others because if you take it way too serious , your plays will not be as good as if your playing for fun and you will also loose the essence of gambling which is to have fun . speaking of pro , your right that it does not mean that you can win by yourself , you cant be a pro with that but to be pro you need to apply or to be recruite by some agency to have a sponsorship
