I can honestly confirm you don't really have to win THAT much to get banned from betting on sports, especially via the apps that are out there because your play can be tracked so easily.

If you get designated as a sharp or arbitrage bettor they will limit you to the point there is no reason to play anymore.  I can confirm I have less than a $9 limit on one app and I didn't win THAT much from them.
