Those which may like to enjoy some level of success when they gamble have no other option but to try skilled based games, and this is because as attractive as it can be to win in the games in which we rely on our luck completely, since we do not need to do anything in order to win, it is also true we have no control whatsoever over the outcomes we may get by choosing this route, meaning we have to discard it and choose the only option left over the table that allows us to have some control over our gambling outcomes.
It's not that these gamblers have no option but to try skilled-based games but rather, they just gave up on the thinking that luck is always there playing luck-based games. In the first place, luck-based games won't be called luck-based if everything can be controlled and manageable here. Switching to other gambling-games is just fine but make sure they understand what they are dealing with.
For me, I don't want these gamblers to give up playing luck-based games and switch to skilled-based games just because they are running out of luck on the former. In skilled-based games, everything is not that easy, and don't expect that the winning chance is high. However, if that gambler is really serious about focusing on skill-based games, soon they can create a good strategy to win at most.
