We can argue sports betting is about knowledge a person has about sports but at the end of the day, a person who merely goes with favorite, will also get his picks often right. So is sports betting actually about knowledge?
Edit: So many people are misunderstanding the word, 'favorite' here. What I meant here is oddmaker's favorite. Suppose, a competition is held between two teams 'A' and 'B' with odds 1.2 for former and 2.0 for latter, then former is favorite, and bettor can bet on this favorite without having iota of knowledge about sports itself and still likely win the bet.
I understand the payout will be less, but here we are saying, getting the pick right without having knowledge about sports whatsoever.
Hope I have made myself clear enough.
Sports betting is still about knowledge of sports, and even if you are right with this analogy that you gave, there is still a downside or a con, or a disadvantage of not have good sports knowledge.
The disadvantage being that the favorite aren't always the winner in every bet, one is that the favorite will always come with a lower odds which means less profit, and sometimes, they may end up losing.
Having a good sports knowledge and being able to research and make your own analysis will give you an edge which is being able to find out when a sports book is making the mistake of awarding favorite to a team that is potentially going to lose the match, this help you bet on the other team with better odds and profit potentials.
