Your tablespace is in automatic segment space management (ASSM) mode. In that case you can't explicitly set PCTUSED, instead Oracle will use 4 freeness levels for table blocks internally (in addition to 2 special statuses), putting block back to "free" status when block usage drops at least one level below PCTFREE.
