No. The diagram https://science.nasa.gov/resource/history-of-the-universe/ tells us that galaxies and dark matter formed 400M years after the big bang. Look at the right of the chart legend: "13.8 billion years" is above "today".

That's the beauty of theories in that they can be proven right or wrong. Thanks to the JWST, a lot of theories are needing to be updated. We're just now being able to actually test those theories. At some point, these types of charts will be updated.

As you stated, it is exciting times.
