Hi,
The 3307 port test has no impact on your problem. We know that port 3307 works correctly for MariaDB, otherwise the service would not start and the Wampmanager icon would not be green.

If you cannot add port number 3307 in the Wordpress database connection procedure, it will not work.
That's why I tell you to read the document "how to use MariaDB" where you should have seen that there is a possibility to set MariaDB as the default database manager, in which case port 3306 will be used and since it's the default port, there's no need to specify it in the connection procedure.
