Unlimited in this context just means you're going to be CPU limited before you hit limits on IOPS. It'd be technically not possible to be bottlenecked on IOPS.
That might not be 100% true, but I've never seen a RDBMS be able to saturate IOPS on a local NVMe. It's some quite specialized software to leverage every ounce of IOPS without being CPU bottlenecked first. Postgres and MySQL are not it.
