is there any way that sub-directory of a domain and its sub-domain work exactly the same way?

For example, I have a domain example.com. Then I have created a subdomain from it e.g same.example.com

I want that, same.example.com and example.com/same/ will work the same way. such as same.example.com/another/ and example.com/same/another will make the same result and so will do any other HTTP request and any further sub-directories.

Thank you.
