Agree, Risso's dolphin are primarily teuthophagus, meaning they eat a lot of squid. It's probably a combination of obtaining scratches from prey items and intra-specific fighting. Some of the beaked whales (Mesoplodon and Ziphius) are also characterized by these same scratches, particularly the males.

Although little is known about these animals, they seem to obtain these scars from scratching in fights with their prey, giant squid, and from the teeth of other Risso's dolphin.
