Well... . DDL will generate small amount of rollback for changes in the data dictionary...
See this:
SQL> select usn, writes from v$rollstat;

         USN  WRITES
       ---------- ----------
                0        716
              2       1472

SQL> get f1.sql

1 create table mytable (mycol number) 2 storage(initial 1M next 1M maxextents 10 pctincrease 0 ) 3* tablespace users
SQL> /
Table created.
SQL> select usn, writes from v$rollstat;

         USN     WRITES
       ---------- ----------
                0        716
                2       3273

SQL>drop table mytable;
Table dropped.
SQL>select usn, writes from v$rollstat;

         USN     WRITES
