How is the Universe bigger than its age?

Re: “And that’s why a Universe that’s 13.8 billion years old has its most distant objects that are visible to us at a current distance of 46 billion light years!”

OK, those objects are now 46 billion light years away, but we are not seeing them “as” their current distance or in their present state. We see them as they appeared, 13.8 billion years ago, but at a distance much closer than that, and therefore larger, than they would at 13.8 billion light years distance, more like 2 or 3 billion light years distance. In fact we are seeing them as closer (larger), than other physically closer galaxies that have younger light. Am I getting this right?
