What is the O365 DLP regex for digit string below (including spaces)?

There are probably dozen different ways to match this string, you can try something like this:

"\d{4}\s\d{4}\s\d{4}\s\d{4}"

If you want to avoid leading/trailing numbers:

"\b\d{4}\s\d{4}\s\d{4}\s\d{4}\b"

If you want to match the actual numbers 1..4:

"\b[1-4]{4}\s[1-4]{4}\s[1-4]{4}\s[1-4]{4}\b"
