No, advantage betting is pretty much only against the houses, not against other players. While people who know the sport and manage to bet misplaced lines can be winning over a season, advantage betting is the only way to reliantly have a positive EV. Casinos and now sport betting apps try to prevent professionals to use this, but with the number of shit you can now bet on, and since you don't have to tie an account to your real identity yet, it is becoming very difficult to catch that, especially if you muddy the water with dumb bets.
