---> Simple question: once I execute the delete statement, does it free disk space immediatelly?
No.  deleted rows (in a sense) are simply marked as deleted and are made avaliable for being
written over by a new or updated tuple.  If you want to recover the space you can you TRUNCATE or
VACUUM FULL & possible REINDEX.
