"Two things that can both be true at the same time: X. Exchanges/PMs are much harder to beat long-term than sportsbooks. (As discussed by @SquirrelSigma below.) X. Exchanges/PMs offer better pricing and recreation bettors lose less than at sportsbooks. How X. To beat one sportsbook only requires beating the team behind that one book (not other pro bettors). To beat an exchange requires beating the market as a whole - the collective wisdom of everyone in the market including all the pros. X. Exchanges with low fees and tight spreads offer better pricing than books. Recreational bettors"
