7. No. It's a study about if they wear mask before they got COVID.

Mask, unless it's N-95, doesn't prevent you from getting COVID droplet. It mostly prevents you from flying your own droplet over the air. So mask is only as useful as the person who doesn't wear it. If everyone does, their own droplets wouldn't get in the air and it would prevent other people from getting COVID.
