That’s not really accurate. Europe uses CCS2 which is completely different and incompatible with CCS1 which is what we have in the US. Recently the US agreed to move to J3400 for dc fast charging with the expectation CCS will eventually go away. China uses a fourth standard GB/T which is incompatible with any of the above.
In my experience, there are at least two different Diesel nozzle sizes in the US, and both are different from gasoline nozzles.

US Diesel cars before about 2013? didn't really care aboit nozzle size. Some diesel pumps had the old standard nozzle size; some had the new, smaller, nozzle size intended for unleaded gasoline. VW started putting in anti-misfueling devices into their cars (via recall for mine), and then you could find which stations had unleaded sized nozzles because it was hard to use those. Presumably, nearly all of those have been replaced with the old standard size.
But then truck stops have giant nozzles for the giant tanks on semi trucks. Those won't fit in a regular car.
I didn't know that about diesel. Regardless, I was hoping we could find some agreement globally .
Right, China and Japan are different. Here's an older map: https://insideevs.com/news/333637/european-ccs-type-2-combo-...
The US went NACS instead of CCS2. Canada and Mexico haven't made a commitment either way.
It would be nice if we could work together and do just one in the same way that we didn't have to worry about fuel pump nozzle geometry being country specific with ICE cars.
