Have you heard of Betfair? A UK company which has done "prediction markets" since 2000. In the Europe it is called a betting exchange and regulated like sports betting. And betting pools is another form of betting which is way older than that and there are no house in them either.
And by your argument poker or backgammon would not be gambling either.

They aren't. A sportsbook explicitly sets lines and you are betting that the line they set is incorrect.
