When a file is deleted, the inode is reused, but inodes are never deallocated. When setting the maximum number of inodes in a file system, there is the option to preallocate inodes. However, in most cases there is no need to preallocate inodes because, by default, inodes are allocated in sets as needed. If you do decide to preallocate inodes, be careful not to preallocate more inodes than will be used; otherwise, the allocated inodes will unnecessarily consume metadata space that cannot be reclaimed.
