I think you're conflating two things.

To paraphrase the docs : You can ship games on consoles, but the tools required to do so will never be included in the open source code.

Eg. Just because you need to buy a tin opener to open your can of beans, doesn't mean you don't have any beans

Did you read it? It clearly backs what I just said. Godot open source doesn’t support consoles because console sdks are closed source, but there’s nothing stopping you from publishing on consoles. They literally list a company who is doing that, more are following. There’s no restriction at all other than you having access to the SDKs which you get when you sign a contract to publish your game on their platform.
