well , lottery pure luck games
Luck is the important things in the gambling game, not just lottery, i guess.
Yea except sports betting all needs luck.
You don't need luck in sports betting?
For sure there are some skills needed and a bettor must take into account various factors, such as player conditions/injuries, their past performances, Are they playing at home or away etc. to predict the outcome of a match but some luck factor is always there. So I think it's the combination of both, Skills + Luck.
