Yes, and they are wildcard characters, and in the case of the Users list table at wp-admin/users.php, those asterisks are being added by wp-admin/includes/class-wp-users-list-table.php (see source on GitHub for WordPress v6.1), so that a LIKE ‘%<keyword>%’ query is performed by default.

esc_url, esc_url_raw or sanitize_url?
