yes, when video game developers talk about 'games' they generally mean video game. It's a convenient shorthand in their community. Much how when a computer programmer refers to a 'file' they typically mean a 'computer file' rather than a physical one, when an electronic engineer says 'circuit' they mean an electrical circuit rather than a racing circuit.

Actually, there's nothing in the rules that limits the competition to video games; I wouldn't be surprised if people had created print & play physical games for previous LDs.

People have in fact done so.

References to "source code" apply only to video games.

Are games not a subset of video games?

edited: the word "video" next to the first games

Is that supposed to be an infinite loop?

Oops, fixed.
