Yes, many of them are regular GUI users.
But also many of them do the same scheme for years now, sometimes for long
periods with the same accounts.
Like the notorious "Maria Elisabeth Schaeffler" mass scam every day.
I do not believe Google does not know what goes on. They just don't care.
Other freemailers care and they are not abused in such amounts.
But if one wants to get rid of the Google scam to some degree:
Many use their campaign GMail as the Reply-To address.
Especially when sending from hacked accounts, but also when using other (new)
GMail accounts.
I have yet to see a false positive while filtering that.

The key problem is that email accounts are free, and the 419 scammers are not
bots, and so it is difficult to prevent them from opening a new account.
Ideally their messages would trigger outbound filtering when composed, but
stopping them must be harder than one would naïvely expect, and conveniently
for the big email hosters, not a problem they need to solve.
The scammer just needs to avoid sending spam to any Gmail users from a Gmail
account, and everyone else has no effective way to complain.
Another barrier to effectively shutting them down is that much of the junk is
sent via various other outbound services, with just the Reply mailbox on Gmail
(or similar). It is then difficult to convice Google to shut down a mailbox
that is not even directly a sender of the junk.
Externalities are great when you're not the one on the hook for the costs.
