No. What you were refering to was the "sprite" a 2D graphic. It has nothing to do with damage tracking and is merely a visual representation of a hit. When you asked if the hit sprites were serverside or clientside you were refering only to the graphic representation of the hit.
As to hit detection, the way that works is that when you get a hit it is sent to the server which then sends it to the client of the person you hit. If you see a hit, you got that hit and the damage will be inflicted.
