With these number of games, they fall on the skilled based type and the luck based type of games, of course you'll choose a skilled based type of games if you want to concentrate on gambling s they don't have an edge, in the long run if you are good enough, you might be profitable.
We have a choice but I think that majority of players still choose luck based games. Some more ambitious gamblers are more focused to skilles but they also work on that skills for a longer period of time, they invested their efforts and time in it. But to be honest I think that even skills based games require a bit of luck to be successful.
