I tend to agree, although I think it’s important to distinguish between short-term outcomes and long-term decision-making.
Personally, I prefer poker and sports betting because I enjoy the analytical side of both. In poker, you can influence your results through strategy, position, bankroll management, and understanding your opponents. With sports betting, research, statistics, form, and identifying value all play an important role.
Casino games feel different to me because the outcome is primarily determined by chance, and there is very little a player can do to influence the result. Of course, variance and luck are still a major part of both poker and sports betting, but I prefer activities where my decisions and analysis can give me at least some degree of an edge over the long run.
