Yes and no
As with every file system access if you delete a file the space that was previously used by it will get “reclaimed” – the free/available space of that file system will get larger accordingly.
The file system itself will not “shrink” nor will the LUN that hosts the file system use less space on the backend.
Please don’t confuse space reclamation for NAS (file) vs. SAN (block)
