It is generally believed that when a team is priced lower in terms of odds, they have a better chance of winning the game. While this is not entirely true, as we do see bigger odds winning smaller odds sometimes. But ordinarily the smaller the odds of a team, the higher their chances in winning that particular game. Also the more people are favouring a particular team to win, the bookie will be adjusting the odds so they don't have to pay much money should the team eventually wins that's why they keep adjusting the odds
