But now I think most Casinos are doing both, so if you are betting in sports they will find a bettor that nearly place the same bet as you and they will either fill your over/under bet or they will do it on the other side. Basically, we are just against other players and casinos are just filling in some gaps, but if they cannot find anyone, or you are just the only bettor they will just play against you.
It might be hard for us to grasp, but they’ve got a solid betting system in place to handle all that. What you’re mentioning is just a small part of the bigger picture in sports betting. They even use AI to make their operations smoother and more efficient.
You’ll notice there are tons of sportsbooks, but only a few odds providers. In fact, more than 100 or more sportsbooks might rely on the same odds provider. This keeps the odds uniform across platforms, making it easier for them to track bets and adjust odds or markets as needed. That’s why we see line movements, it’s all part of the system.
