Do martial artists walk differently?

Last night I saw someone in this sub mention a strange exercise he does where he walks like a penguin and it reminded me of something from a few years ago. One of the people at my dojo was saying that she thinks martial artists walk differently than normal people. The instructor disagreed, he said he walks like his dad and his dad has never done martial arts. I remember thinking that, I did kind of walk differently, a lot of times back then I wouldn't so much step, but rather slide and glide but it was kind of deliberate, and I think more influenced by a tv show than my actual training (in my mind I thought it was more stealthy I guess), plus probably also due to my gi pants being longer than they should be (when I got the new gi I went up two sizes instead of one because I didn't realize the gis also came in odd sizes). I don't know, does this seem plausible to you or far-fetched?
