Valorant betting odds

I have never betted in my life and Im not promoting it or any betting website, but I checked some most popular betting sites and most of the odds were crazy. Navi had at least 7-8 odds in most of them, I mean they were the underdogs but they werent expected to be that bad. Even oxygen had at least 3-4 odds in most of the sites and they were literally favourites against VGIA in my opinion.
Like upsets happens every tournament and if I bet the same amount to matches that has underdogs with at least 4-5 odds and still has a chance to win then I will win more than 50% of the time, those odds were literally trash. They should hire some analyists for the odds but I think they are just looking at stats and opinions of 13 year old fans in twitch chats or internet forums. Am I wrong?

odds are based on amount of money put on each side, its not any analysts or stats, its just how twitch predictions work

Do you think betting site odds are based on analysts? Bookmakers have an edge on every bet, they can literally not lose. And the odds are decided by how much money people put on each team.

I have made bets on valorant recently and the odds they have are usually pretty accurate
