This jam is certainly only for table-top role-playing games (TTRPGs). I don't want to be too prescriptive with what I think a TTRPG as the category includes everything from strategic, combat-oriented games, to collaborative and GM-less story games, and the purpose of this jam is for people to experiment with different designs.
In my opinion, Gloomhaven, Hero Quest, and Monopoly are not TTRPGS, they are board games. However even if you disagree with that interpretation (which is totally fine) they are certainly all beyond the scope of this jam as they have a board, cards with extra information on, etc. and aren't able to be run with a single page of rules.
