Is roof felt actually waterproof

Just wondering how much protection felt really gives under the tiles. Does it stop leaks on its own or is it more of a backup layer?

"It's a backup layer for when you have a broken tile, in the middle of the night for instance, and gives you time to get a repair done before your house and ceilings are damaged."
