No, ZFS tries to solve the problem of data integrity mainly. It also supports very large volumes and files, but it's not particularly good at storing billions of files in a single one. In that respect it's like any other file system. It'll do it, but you need to design your directory structure well to have fast access, and if you try to copy the directory structure it'll still be very slow.
