How do you get these numbers from the win probability?

Those are based on current betting markets, which price the Eagles at -125 and the Chiefs at +105. -125 implies a 55.56% chance to win, and +105 implies a 48.78% chance to win. That sums to more than 100%, as the sportsbooks factor in a cut (or "vig") for themselves. So you have to adjust those back down to 100% to determine actual sportsbook-implied probabilities.

Not sure where you're located, but the way betting odds are presented can vary quite a bit from place to place. -125, +105 are "American odds." The tool I've linked to below is a nifty little way to convert these to decimal odds or British odds (both of which are more common internationally), as well as to win probabilities.
