It's obvious that even bookies make mistakes in their selection of their odds like in the games between the Chiefs vs Eagles and we can say that it was the underdog that really prevail. But I believed that there are fans who bet on the underdog here, for many reasons, i.e. they hate Mahomes and the Chiefs,

No I didn't bet on the Eagles though, although I did follow the results and I was happy that the Eagles won this time. Of course, this can be applied in any other sports. That you can look at the underdog and see if they can pull a big upset. But not underdogs though will win, and this is the very definition of gambling we really don't know the result and maybe we have the gut feeling to bet on the underdog and win.
It’s not a bookie mistake rather those odds are based on the popularity of that outcome to come through. Bookie doesn’t guarantee that their odds is the basis of what will be the outcome rather they grade it in consideration with their profit.
Most of the bookie error are those matches that was assigned odds a little bit higher than the regular odds for the match that gives room for value bet and arbitrage bet but a simple odds placement on a favorite team is never an error from bookie side because that what the stats dictates.
