Does it have "fake" tensor cores? Aren't those for training?

You still need tensor cores for inference. But they don't do weight updates. Learning/training is all about updating the weights (through backpropagation or whatever).

So another way to put it: its tensor cores do feed-forward calculations, but no backpropagation, and no weight updates.

The hardware and platform is capable of training just fine. It's just rarely done because it is slower than training on pretty much any discrete GPU.
