It tells us that the training data mostly consists of male statues because most pictures of greek statues are male (source: google and ddg searches). Also, when most people think of "Greek Statue", they think of something like what was generated. That is all there is to it.
Does that explain how small their dicks were, or we going to stick with the story that large ones (and those not covered by the prepuce) were considered rude and mockable?
