Luck and skill are always related. If only relying on the luck factor related to success in gambling, I do not believe.
Sports betting is very much related to the skills in doing it, later the matter of luck will come along the way because sports betting cannot be separated from analysis.
In sports betting, the percentage is 60:40. The percentage of skill is greater than the percentage of luck in my opinion.
Skill needs to be singled out from luck, and in terms of sports betting, skill appears to play the major role in most of the games, whereas the player will have to use his skill to figure out which option and which team have a higher chance of giving the player the winning they want to bet on, while luck will just have to sum it up based on the work skill has been able to do by giving luck a soft landing position.
