What do these numbers across the skills mean?

When watching other players play Smite, the UI sometimes looks different from what I see. For example, in this screenshot, there are extra numbers across Anhur's 4 skills:
I know that the top numbers correspond to the keys you press to use the skill, and the numbers centered on the skill show the remaining cooldown. What do the numbers at the top of the skill box (80, 110, 80, 120) mean, however? I've never seen those when I play.
