readlink just provides the name a symlink points to. It doesn't resolve any symlinks in either the symlink's directory path, the directory path of the target, or if the symlink itself points to another symlink. realpath works on any file, collapses .. and . references, resolves any symlinks in any path component, and provides as its final answer an absolute path containing no symlinks.
