The house always wins because even if a player wins one or two games he will be losing in other games. The fact that lower odds are provided or a team is tip to win doesn't mean you will win.
If you want to have a decent chance in gambling, choose a game where there is no house advantage.
Good example is sports betting, there is a juice but you can increase your odds to receive equal of your bet or even higher.
When you play a game that has a house edge, just do it for fun as you have no chance to win in the long run.
