Do imports to MailChimp get added to WP users?

MailChimp Sync is working. It imported all my WP users. Now, I need to import my AWeber subscriber list to MailChimp.

No problem importing the CSV file into MailChimp but before I do the import, I have a question:

Will these imported AWeber subscribers also be added to my WP users?

If not, what are my options? The AWeber subscribers will want to be WP users and many of them already are.

Thanks,

Ed
