See attached screenshot.
Import summary reports on "Total Rows" which is actually the number of contacts imported, and "Records Imported" which is actuall the total Rows form the Import file.
The two numbers can be different when a row generates multiple contacts, e.g., by including an 'Employer' which is mapped to an Organization Name.
I propose these alternate labels & descriptions:
Total Contacts (Total Number of CiviCRM Records created or modified by data in uploaded file.)
Rows Imported (Total Rows in uploaded file which successfully created or modified one or more CiviCRM records.)
