Well, this is what makes them profitable if they have the discipline to manage their funds effectively.
I am not a fan of poker but I know some people in our community who are always in a casino to gamble and play poker, maybe they are having success but I wish that's my interest too, I just love sports betting but that either is not something I can call a profession.
Yes, I forgot to mention that, without any doubt, sports betting is something that doesn't depend on luck entirely. In fact, since recently, I've started to think that the part that skills play in sports betting can be compared to that in poker, in the sense that they both pretty much depend on skills. Of course, we cannot exclude luck from the equation for both. It still plays a big part, and thus it's risky to choose either poker or sports betting as your profession, but we can't ignore the examples like Billy Walters and Daniel Negreanu, who have earned tens of millions of USD through sports betting and poker, respectively.
