No, what the spec does is say that if the cable doesn't have a max rating, it'll top out at 5V (and .5a, I believe).
Then, it does negotiation with the cable and the device to insure that it can provide the voltage the device needs.
And yes, PSUs MUST negotiate voltage or be 5V only and all USB-C devices must accept at least the 5V voltage.
