As someone who does hiring and reads resumes and has also run D&D games since high school, no, not really. It means about as much as if you told me you were in the chess club.

People talk about D&D being a way to show good people skills or whatever, but let's be blunt, assholes also play D&D. Groups of them do occassionally. It's not typically a job, you aren't generally being managed while doing it, and your peer group will largely be made up of people predisposed to enjoy the thing they're doing.

Outside of DMing professionally as a job (on a schedule, with clients who can fire you), with references, it just doesn't say enough to move the needle.
