If you think about it, then excitement is present in any sport: tennis, football, basketball and so on. The main difference is that gambling games are different. If you consider, for example, a casino or slot machines, then the mathematical advantage is initially on the side of the gambling establishment. But poker is a little different, here the chances of winning are equal for all players, and in the long run the winner is the one with more experience and more gaming and personal skills. Of course, there are unlucky and unprofitable days, but an experienced player has many times fewer of them than lucky and profitable days. If you look at this topic superficially, then yes, poker is a game of chance. But if you delve deeper and understand the nuances, then poker is a whole science and a separate world that can be studied throughout your life. I can’t say anything about trading, since I am not deeply familiar with this field of activity.
