Betting odds
For those who are not familiar with the matter, the question may arise, why are the coefficients so important? If I guess the winner correctly, it's still a win regardless of the odds. A better Odds is just a bonus if I'm right in my guess.
It is good to break away from this way of thinking right away. No one can know in advance the result of any match. It is only possible to make probability estimates, and the offered coefficients must be compared to these probability estimates. Also, correctly "knowing" the individual match does not tell you anything about the goodness of the bet, if you "know" Canada will win, and therefore you do not even bother to look at the odds and Canada also wins, then you have played badly, even if you have won.
Let's use an example: If Canada and France face each other in the hockey World Cup, then Canada is the overwhelming favorite. Someone could even consider it a sure winner in such a match and therefore take it with them to the combination bet slip without even looking worse than the odds. However, nothing is certain in hockey or in sports anyway. For example, if we consider that there is an 82% probability that Canada will win (which is about the same probability as the best hand in poker, AA, hitting a lower pair on the board). A beginner might think that "yes, it will win after all", but a professional bettor starts to compare the probability with the odds offered.
This means that if the company does not offer Canada a higher multiplier than that, then it is not worth placing a bet on behalf of Canada, because in the long run you will end up with a loss. For example, Finland, the reigning ice hockey world champion, lost to France in the opening round of the games a few years ago. That is, even though Finland's victory was completely certain in the opinion of many bettors before the match.
Technically, the coefficient shows the betting company's probability estimate and compares it to your own probability estimate. The smaller the coefficient is, the more likely the evaluator sees that outcome in the target. If a result was completely certain in advance, then the coefficient would be 1.00 (or actually less than that, since the betting company has its own deduction for each item).
Odds can also be misleading, a player easily seeing a good odds at first glance starts to favor his preconceptions in his analysis and the probability estimate may become inaccurate. That is why it is of the utmost importance to make probability estimates before familiarizing yourself with the available odds.
