Sportsbetting is only an AP play if it involves more than just selecting the game you think is going to win.

It's an AP play if you have found a way to do it where you have a legitimate edge.

Examples of this:

- Prop bets with wrongly set lines
- Betting based upon information the book does not have yet
- Taking advantage of stale lines which haven't been updated at a book, allowing you to bet both sides (at different books) and guarantee a profit

You can also be a winning sportsbettor by just being better at handicapping than the books (and enough to beat their juice), but that's not what would traditionally be referred to as an advantage play.
