Maybe they're deep because of water erosion from rains over a thousand years, those bricks look pretty polished.

I don't think the bricks are that old. Maybe a few hundred years or so

Also, wouldn't water erosion make them less deep not more, due to generally smoothing the stone?

Maybe water pools in them long after it dries out on the surrounding brick, but whether still water still erodes stone I don't know.
