Ext4 has 32-bit/~4billion max limit per filesystem, newer filesystems like btrfs have a 64bit limit. Neither allocates the whole max size by default. I don't imagine Google drive uses an out of the box filesystem underneath though.

Btrfs is particularly special as the inode limit is per subvolume, so it's quite easy to have an impractically huge number of them with some cleverness.
