Jack, you have received a great many responses with the standard
explanations along with their caveats, applicable to some quasi to
non-existent realities proposed by these models...You didn't buy any...

ahaha.....Now, let me sell you something that is intuitively acceptable.

Accept or believe that the universe is ~ uniform in its matter density
and that it is much, much larger then the PORTION we can see of it.
Accept that the total universe stretches much much farther out then to
the ~15 BLY away from us in any direction from our place right here.

But, within this "visible" sphere, lit up by starlight, which is ONLY our
visible portion of the total universe, YOU are obviously exactly at its
center, the center where YOU do you stand right now , fart and look
and ogle from.

Now, if the universe is much larger then 15BLY, then wherever you go,
even out to the 15 BLY limit from where you stand now, you will be
still in the center of a (new) sphere of a 15BLY large universe. You
are simply IN THE CENTER OF ANOTHER PORTION of the universe (in
our cosmos that is much, much larger then our visible portion of it)
....and you could drive this scenario (and your movement) on forever
and you still will always be in the center of what you see. Ergo, the
center of the universe/cosmos is everywhere.... or "all points" are centers.

It's a bit like you standing at night in a vast field of fog about which
you have no idea how large it is. Now, wherever you point your
flashlight to, you will see by your beam, that it is reflected by a "light
wall" within this fog. You realize that you're right at the center of the
sphere that you have lit up with your flashlight. Now, no matter
where you move to or wander around.....you'll always be exactly
at the center of your own lit up fog-universe. --- Conversely, if
there were many other light carriers, like you, strewn around in
this field of fog, you'd only be able to see them when they do come
within the radius that you yourself have light up. Hence, that lit up
sphere in this sea of fog is your personally visible "universe" portion
of/in that vast fog universe. And you are always at the center, no
matter where you go, because the fog always extents to much farther
then you will travel.....

Now, consider that the fog, you are in, is beginning to thin. Then
obviously the water droplets are getting further apart -- same/similar
to/with the cosmological models: Replace the waterdroplets with
galaxies and you have your "expanding universe" models.

Caveat: Remember, ALL these theories are just stories about nature.
**STORIES** that more or less confirm what we (like to) believe to
have experienced. But the actual reality of it all may very well be a
very different story whose borne is hidden from us by fiat...........

Are you at center now, Jack?........
Of course you are. Not only spatially but at ALL TIMES to boot!..ahaha..
ahahaha........AHAHAHAHA......ahahahanson
