I'm not sure it's all that more likely than decapitation. For a combat to end in Injury, it requires a very specific number of hits, while the Decapitation just requires a minimum number of hits.For example, when the defender is down to 3 dice, an injury only happens if the attack causes exactly 2 hits. But if the attack causes 3 hits, or 4 hits, or even more hits, then it's a Decapitation. Also, there are some weapons and gladiator abilities that allow the attacker to fine-tune the attack to add a hit, which can allow him to land a Decapitation easier if that's what he has bet on, while the other players who picked Injury get nothing.
Overall, Injury may be a tad more likely if someone crunches the statistics, but it's probably not significant enough to warrant a 3-to-1 payout for Decapitation, I'm guessing.
