Mars is constantly shifting and changing with its weather and seasons. Ice caps freeze more, and ice caps melt more, water or other liquid flows down hills when it gets warm.
More often than dust storms, a new robot comes down to land on Mars in firey rocket-landing-fueled or bouncing-ball style. Movement.
Mars is constantly hit by rocks from space that create craters and push dust up into the atmosphere.
I've never heard someone say "Nothing ever moves on Mars" because it's really not true and a total lack of imagination. Maybe people think nothing moves because we haven't sent video cameras yet? But...Mars is constantly in motion.
Earlier this year I made a video[0] where I took two images which are frequently posted on reddit that show the movement of martian sand over a day and interpolated (with python and opencv) the movement into a smooth video. I'm currently working on restoring some Apollo footage, but one of the pending projects is taking the Curiosity descent sequence (at 4 frames per second) and give it a shot at some nice quality, XXI century interpolation (we have some very good algorithms now, or at least better workarounds the artifacts).
The creator on that channel simply uses a DAIN application without pre or post processing the images (either the base images or the optical flow maps).
I take a different approach and I can't say I haven't found issues (I have, many, I'm working on them).
My goal is to reach a level where there are almost none artifacts (there are a couple in that video at the start, when the shield is released and when there are many large movements of the camera due to Curiosity dangling off the parachute). As I said, I'm still working on it, and in between my other side projects, work and quarantine I've been on a less-than-ideal situation.
In time, if I pull it off, I'll post it and I guess you'll see it.
When something is quoted like that it usually means it's a reference to something, not a literal statement. In this case I'm guessing it's a play on "Nothing ever happens on Mars" by the Spinal Tap guy.
Here's a dust devil https://www.youtube.com/watch?v=k8lfJ0c7WQ8 (again, it's still images to make a video) but not because "nothing ever moves on Mars"!
