We are using Oracle Database 12c 12.2.0.1.0
I understand from documentation that GLOBAL_STATS are applicable when tables are partitioned.
I see from all_tables that tables are not partitioned in the schema, PARTITIONED=NO
But I see from all_tab_statistics GLOBAL_STATS=YES and USER_STATS=NO for all tables in the schema.
Do I need to gather statistics again ?
