If you are able to beat the house in the odds calculation is how you win money in the long term, which is becoming increasingly difficult especially in major sports.
I highly agree! I believe the chance of winning on the 1.90 odds is not dependent on the odds alone. Even if it has more than 50% chance of winning theoretically, there are other factors that affect the result of the match like the condition of the team or athlete on the day of the fight, the unknown factor that can affect the result of the game and more.
At the end of the day, the actual chance of winning is dependent on how a bettor assesses the possible outcome of the game and not the given odds by the bookmaker. So it is still not sure whether betting on these odds will be profitable in the long run unless we can precisely predict the outcome of the game.
