Winning big in sports betting is difficult because you need to predict multiple outcomes simultaneously. Winning a larger amount is easier with slots because the game offers frequent small wins, and our brains react by releasing a sense of reward.
But given all this, I have a question...
Does this feeling of easy winning make people gamble more than they should?
People really do tend to measure their "luck" in units of "gut feeling". It really is a silly way to lie to yourself. Or maybe I should call it self-motivation to lose more money?

Mathematical probability can be accurately calculated, yet people would rather believe in luck than in logic.
But you are right about slots offering smaller frequent wins, which is why a person tends to feel luckier with slots than they do in gambling. And yes, the release of dopamine in our brains do tend to trick us into actually believing our own poppycock.
