Some older context is they price per CPU core and I remember something like $10k/CPU core per year. This is from years ago and there were "enterprise" agreements in place and many millions of dollars being spent. I can't imagine they lowered prices other than maybe cloud offerings.

The support contract costs more than the "license" if my memory serves me, but its very expensive. If you're doing anything remotely complicated, using their advanced tools beyond a basic RDBMS (replication, clustering, etc.) then you need that support contract.
