As long as you claim to be a professional gambler,this means that you are an addict,because to be a professional in something,it means that you are into it always. As for gambling one must not try to be a professional because it is impossible to be a pro in a game of luck. When you have that insight that you are a pro,it will not make you accept loss easily because you will feel that it was a mistake that made you lost the last game and you will want to chase your loss. During the process of chasing your loss,you are getting addicted gradually,till you will no longer be able to live without gambling.
I do not agree with what you say and not all professional gamblers and being a professional gambler does not mean you have to be an addict.
Professional gamblers here do not mean chasing profits but more precisely professional gamblers have various strategies to gain profits by minimizing losses and always have a much stronger consistency than ordinary gamblers and usually professional gamblers make this bet in sports betting and I'm sure you know what I mean.
So this professional gambler is all about betting responsibly.
