No, they don't.
Oddsmakers don't try to predict the outcome of the game when setting point spreads. If a team is favored by seven points, that doesn't mean that the oddsmaker necessarily thinks it will win by seven points. The oddsmaker's goal when setting the line is to keep an equal number of bets on both sides of the game. The betting public's perception of the game can be as important as the actual comparison of the two teams.
