AI has to depend on the data, it doesn't randomize. This means that it would try to do research and weigh people's opinions, bets placed, interviews with players and teams and draw a conclusion from it.
You can do the same thing if you want or go with your gut feeling but I'm positive that the AI would always choose the stronger team to bet on. It would never go for the underdog because statistics tells it that the team that has 70% to win should be chosen, right? This means that in the last FIFA World Cup it would bet on Belgium vs Morocco, and about 90% of bets in that match was for Belgium, but it lost.
such information which did happen in the past and it wouldnt be able to caught up with the current or recent events which they would be automatically be able to put it into their library or database.
upsets could really happen and there's no one whether a human or ai could able to predict these scenarios or situations which it isnt really something that you could
handle it out.
Nothing but to agree with your statement, upset is always present in any sports and even with the help of AI we really can't tell when upset will take place, in regard to how AI will work I also agree that they will base their judgment with how the team or players being written from the paper stats which it will be based from the past plays and games that they've got.
We can't tell how accurate AI can be but the advantage that I can see is if you are a fan of basing your judgements with the advantages of your selected players or teams then AI can help you to lessen the research, it will save you time in doing it with the help of AI.
