yes, this is the point!
the house edge plays a huge role when it comes to luck vs skill games
I think the same that knowing the game could give you an edge on sports betting
but probably a really small edge since there are so many variables, what do you think?
The edge depends on how skillful the gambler is, even a small advantage could already make a person profitable. In general, I consider sports betting as a skilled based type of game, but if a gambler does not have knowledge of the particular sports he is betting, or even just a small knowledge only, then it should not fall to the skilled based classification on his level.
