It depends on the type of gambling being played. If it's sports betting, I think what matters is the odds, not luck.
Both odds and luck can be important in sports betting. This happens when gamblers choose to place parlay bets. When a parlay bet is placed, relying on odds alone is not enough; luck is also a factor.
If one or two matches go as expected, the outcome of the other matches may not be as anticipated. If the bet on the third match loses, the entire bet will be considered a failure.
