Empty table in DBA_SEGMENTS

Hi All

Kindly, I have an empty table with zero rows, when I try to check the size of the table I can see it's 1 GB,

MY DB 11.2.0.4

This is the SQL I am using to get the table size:

SELECT Segment_Type      ,Owner      ,Segment_Name      ,(Bytes / 1024 / 1024) Mb      ,Tablespace_Name  FROM Dba_Segments WHERE Segment_Type = 'TABLE'   AND Segment_Name = 'EIM_SRV_REQ'

Is this statement correctly showing the table size?

Is this 1 GB consuming space from the tablespace? if yes, should I execute any statement to shrink the consumed space?

Thanks ...
