404 error pages, and specifically .htaccess rules do not work across subdomains. They one work on one domain, and one domain only. If you want them to work on other subdomains, you need to create the subdomain in the control panel, then upload the .htaccess file to each new subdomain.

No,
I’m Ok with that
But If https://sub.domain.com where sub subdomain that does not exist
I want in that case

You can’t do that without access to the server. Please read my above reply about how .htaccess works.

If you want to show a custom page on non-existent subdomains, you’ll have to find a hosting service that allows wildcard subdomains and setup the parking page there. Then, in your DNS at Go Daddy, you can point the subodmain * to that hosting service.

And if you just don’t want to see the parking page people see right now, you can delete the current DNS CNAME record for * and people will see a DNS error instead of this parking page.
