Gamebooks ("Choose Your Own Adventure" is actually a trademarked Gamebook series by Bantam, like how "Fighting Fantasy" is by Steve and Ian. We know them as CYOAs because anyone in NA before the age of internet. - Plus many after that. - probably would have owned at least one in their life.) are as close to Tabletops as, well, how Console games are close to Tabletops.
Forum-based games like the pic above are not gamebooks, in that you only ever get one final decision even if different choices are given at any one time. Those are essentially freeform TRPGS in a different format. We just call it CYOAs for convenience sake.
How one terms it ain't really matter though.
