I think it's only natural that some gambling platforms favor Liverpool and I wouldn't be swayed by their favorite. As long as the match hasn't started, there are always surprises, whether it's predictions about who will win and who will be the scapegoat. Basically the odds of both teams are 50÷50 as long as the game has not started.
Chance based on assumptions and odds are completely different. It's true that Liverpool and Real Madrid are both likely to win the Champions League title this season and it's probably 50:50, but when you talk about odds it seems Liverpool are the favorites in the final this season. Temporary odds: 2.12 - 3.65 - 3.30, Based on this, Liverpool may be favorites to win the title over Real Madrid.
I hope I don't misunderstand your post, especially about
As long as the match hasn't started.
