“They’ve got the math on their side, the only time they lose is when somebody monkeys with it.”
And IF they have not balanced the bets.
They ALWAYS balance the bets. That’s entire point of odds and spreads and all that. None of that stuff has anything to do with how they think the game will go. It’s just to make sure that nothing ever happens that makes the house lose. The house owns the odds, the house ALWAYS wins, anybody that tells you otherwise is probably working for the house and trying to get you to be more.
