That’s correct. From what I’ve read during my research on the over/under market, experts often say that the over is usually the public’s favorite pick. That’s why bookies tend to set the line in a way that makes the over look more attractive  but in reality, it’s often a trap, and the game ends up going under.

AFAIR, the over has a lower winning percentage compared to the under. I don’t have the exact data to back it up right now, but that’s what I’ve consistently seen mentioned in betting discussions and analysis.
