As far I understand gravity holds the air back down, but surely it isn’t like a seal where air can’t escape

Vacuums don’t suck things, it’s just that things that can move around (like air molecules) are more likely to spread out because some of the ones on the outside are going away from the center. It’s kind of like if you released a bunch of ants in the middle of a room, eventually they’ll spread out just by moving in all directions.
