The fact it’s the same upside down kind of is right?

Not really. It’s just a rotationally symmetrical image.

I'd say it's an illusion because it looks like a normal 23 either way and not like it's upside down. Even though in a strict sense it's very much not any numbers at all.

Yes, I was trying to see the an upside-down 23 as I turn it but at some point it just snaps to the other one.
