But there's a difference, betting on lottery, purely based on luck, putting a parlay in sports betting, you are betting using your skills and knowledge and if you are lucky as well, that's where you win. No one put a huge parlay by just picking the bets blindly, my 2 cents.
That's why as a sports bettor, we appreciate big parlay than betting on a lottery, personally I am doing that and that's the reason I posted this thread because I was inspired by the big winnings of the sports bettors.
