I run an Ubuntu server where the usernames are numeric; they are in fact the student's ID number. I've never actually encountered a problem with usernames being interpreted as UIDs.

Is the system configured so that the numeric username is also the UID?

No, the UID is calculated using the macOS method, which is to take the result of the first 32 bits of the Active Directory GUID AND 0x7fffffff.
