Pretty obvious that it was Drake.
It was an ironic scene, since Drake even said "Only 1%? I pity that guy", when it was actually him, who was being talked about, all along.
Hawkins knew, that all of them were targeting Drake, and also knew about the upcoming ambush. That's why he checked Drake's odds in the first place.
Drake became so desperate in the end, because then he realized that those 1% were meant to be his chances of survival.
