Amazon uses AWS for some new stuff. New AWS services high up in the stack like AI services run mostly on AWS. Most infra-AWS services run on foundational AWS services like EC2 and S3. Foundational AWS services (EC2, S3, DynamoDB, etc.) don't run on AWS for obvious chicken-and-egg reasons. For all of the things that are done by latecomer AWS services you can count on there being an unrelated internal tool, since clearly Amazon was doing those things before they launched those services.
I think the only needs that are likely different are scale, so bigger instances, and the fact that they have a massive legacy infrastructure that can't be easily migrated off of. So that's pretty much what I would expect; Amazon.com does use AWS for new stuff but is still operating a lot of legacy as well.
