Don’t forget the klick. Most of them are not buying that either.
The people in all the countries that have no problem counting off another dozen past twelve don’t always do that though. If you meet your friend at 15:00 most people will revert to “at 3” in their language. And they might “go to bed at 11.” Economy of language and context clues. So colloquially the am/pm crowd and the 24h folks aren’t far apart at all.
And any person claiming that it’s too difficult to add or subtract twelve from at maximum a low two-digit integer ought to have their passport revoked.
