But not everyone knows sports betting or poker or any other games that "require skill," as you said. This is why slots are found by some people a good game for betting. The simplicity of the gameplay makes gambling just a breeze. Yes, the RTP is low, but the thought of hitting a big win on a random spin is attractive enough to make you take a shot at the jackpot, esp. if the slot has a progressive prize pool.
Not every person considers himself lucky enough to play only in slots. In this case, very little depends on the particular gambler.
The desire to reduce the influence of randomness is what drives most players who prefer sports, poker and blackjack.
The ability to analyze the situation, to know the enemy is much easier to master than to attract good luck, experiencing different mathematical strategies that do not work.
