Another observation about luck-based games that a new gambler with an interest in them has to know is that they have the potential to make you, as a gambler, spend more money gambling than skill-based games.
What do you think?
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.
