2nd / 3rd world notions have nothing to do with GDP. There are plenty of countries (a lot of the middle east for example) that would have back when 2nd and 3rd world were relevant notions been considered 3rd world, these currently have some of the highest GDP (PPP Adjusted) per Capita ;)

Sure, but I responded to the comment about “getting on a plane” and discovering that all countries are so very similar.

Yes, but the parent didn't imply that the two necessarily correlate. All you showed was that developing countries can have a high GDP. Are there any countries considered first world that have a low GDP?
