Depends what you consider a "real fight". E.g. I remember a Taekwando instructor saying that BJJ would always beat Taekwando in a UFC match, but he'd never want to rely on their techniques in a bar fight where there might be broken glass on the floor.

I think they mean a more traditional "real fight" - in ancient/prehistoric times, on soil or sand rather than concrete with broken glass.
