Information in this document applies to any platform.
When we delete the rows from the table using the DELETE command, the extents that are allocated to the table will not be released and the table still holds them, whereas when using TRUNCATE with DROP STORAGE clause (which is default), it will release the space back to tablespace.
But we see cases that event truncating won't release the space back to tablespace.
