wp_users table name changed in PHPmyadmin, can't edit user and password - due to hack?

Hello, after cleaning up after a hack, where they created new users on my WP site which I deleted, I found that in my PHP I can't edit user and password as the values are not visible, and table is named "wpk1_b2s_user":



but on my other site within the same server, I have 4 tables and it's working normally in "wptp_users":



Help me understand, should there 4 tables instead of 3, does it mean I'm hacked or just some other thing
