Those odds are in the confusing “American format”, in which a positive number is “how much would you win (in addition to your bet amount) on a $100 bet”, and the negative number is—careful here! -- how much would you have to bet in order to win $100, again in addition to getting your bet back. There are calculators to get the equivalence, since—especially for the negative odds—it’s not real intuitive. So a 50⁄50 event should be +100 each way, and of course it never is. In this case, −160 would be fair odds for a 60% chance event, and +125 would be fair for a 44.4% chance event, giving a “hold” of 4.4% (60+44.4 − 100), which honestly isn’t terrible as such things go.
I think the %win thing on that screen might be from a different source than the betting odds altogether in this case; the classic 50⁄50 bet is generally priced at −110/-110, which works out to a 4.8% hold.
You’ll note that because of the way the +/- odds work, it’s really hard to instantly grasp how good/bad most odds are. (It’s not “halfway between the two”, for one thing.) In Europe/Asia the common format is a decimal number telling you how much you multiply your stake by, including getting the stake back, so those would be [checks online calculator] 1.63 and 2.25. The single advantage of the American system is that you can see what a fair bet should be, because one is just the negation of the other. (For two-way results.) In this case it would be +-138.5.
