yes, I think poker is a sport. Tournaments are a competition in which the best is determined, there is a standings, among all the participants who took one place or another, and also, like in sports, those players who performed best win money.
can you tell me what about the luck factor in poker? I can say that in sports you need luck, you can't win without it. even the strongest athlete who is a head taller and stronger than others needs everything to work out to win
if the player is the strongest, this does not mean that he will constantly beat the weak or will constantly win for each strong one, there will be stronger and weaker in poker.
