Luck-based gambling, like slot games, takes little time to finish. You might spend so much money within a few minutes and wouldn't recognize it unless you are conscious. As you said, sports bets take more time to analyse and predict.
Football games take approximately an hour and thirty minutes, which is time for waiting for the outcome. But in slots in seconds, the results are out. Thus, I accept that gamblers might end up spending more on luck-based games than the other. But some gamblers spend so much on sports games, so my conclusion is not sacrosanct.
Gambling is a complex combination of luck and skill. In games like roulette and slots, luck is the dominant factor, with the outcome largely based on randomness. In games like poker and blackjack, skill plays a greater role, with players able to make strategic decisions that affect their chances of winning. However, even in these games, the element of luck cannot be completely ignored, as a single unexpected card can change the course of the game. So, it can be said that gambling is a game that requires a combination of luck and skill, with the importance of each varying from game to game.
