Advice for a first time GM introducing non-gamer mom to cyberpunk

Hi! Ive never GMed before but Ive been interested in it, and Im getting my first shot by playing with my mom, who's never been a gamer (table or video) but was fascinated by cyberpunks setting and the realization that not all tabletop games are DnD. Any advice on how to get someone into the game who's probably going to be intimated by all the numbers, and also advice on how to GM a one player game?
