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.
