Question about how Hubble can see objects from soon after the Big Bang

So there's this article today that says:

The light we are seeing from them originated 380 million to 600 million years after the Big Bang, which cosmologists estimate happened 13.7 billion years ago.
I have never understood how this is mathematically possible.

The universe is expanding at less than the speed of light.

So 600 million years after the Big Bang, it should have been less than 600 million light years across.

So wouldn't the light emitted by these objects then have reached the limit of the universe not more than 1.2 billion years after it was emitted?

How can that light still be traveling around anywhere for us to see it?
