I would presume AWS is so large these days that Amazon retail's infra is only a small fraction of the fleet?

Published data on their scale is thin on the ground, but this post from 2017 guesstimated that they had 4 million physical servers at the time, and AWS certainly hasn't shrunk since then:

Amazon retail's total combined capacity usage can on most days fit entirely into the spare capacity that AWS keeps available for spot and burst usage by other customers

This article is about how much profit from Amazon comes from AWS. Not how big of a 'client' Amazon is in AWS itself.

Well, if you read the parent comment here again, I hope you can understand that "how big of a 'client' Amazon is in AWS itself" is _precisely_ about estimating profits for AWS.

The fact that Amazon is self-serving AWS resources is obfuscating profit calculations or estimates as there is no way of determining ROI on assets Amazon consumes itself - most likely in a somewhat shared model together with other, actually paying customers.
