Answer

du is used to estimate file space usage—space used under a particular directory or files on a file system.

df is used to display the amount of available disk space for file systems on which the invoking user has appropriate read access.

After deleting a file, the disk space occupied by this file will be slowly released.

The result of the command du doesn't include the size of the deleting file.

But the result of the command df includes the size of the deleting file due to its disk space is not released immediately.

So after deleting the file, the results of df and du are different until the disk space is released.
