Winning at sports betting does not only depend entirely on luck but you are right where it also requires pretty good analysis too, because it is impossible for bettors to choose randomly and hope that there is a goddess of luck who will help the bet become a win especially for parlays.
I disagree. It's completely possible to win just because of luck in sports betting since I won several big parlays that way without doing any sort of research whatsoever.
The biggest example to prove what I stated is a woman who placed a huge parlay comprising of team names that she liked and it came through. She won millions because of it which made this story very famous.
Funny thing here is that her husband is a punter too, but he never managed to win big despite all his research.
