Overlays are any graphic that is overlaid (get it?) with other content - like your camera, game, or chat. Full Overlays fill up the entire screen, aside from cutouts for your game/cam. Overlay Elements are individual graphics that can be moved around - like a cam border or stream labels bar.
Note: I do not include Alerts in Overlays - but I do like to design them together since they share the screen.
