The hook is a ridge that faces towards the tire at the edge of a wheel. It’s small but the hook catches the bead of the tire helping with tire retention. If a wheel is hookless then there’s no hook there and instead the top edge of the wheel is flat. Rather than the hook catching the tire bead, the tire presses against the side of a hookless wheel. This is the same way that car tires work.
huh, I thought car rims also had this ridge for the bead to sit in.
From the article description I think the car tire has a U shape, or maybe think of it as a J shape for the bead. The hooked tires have a G-ish shape, where the top of the outside of the bead wall has the ‘hook.’
What is a hook? Not a spoke hook like I thought.

I just did a quick search, and I think that’s exactly it: https://blog.flocycling.com/carbon-wheels/hooked-vs-hookless-rims/
