Liechtenstein and Vatican City are proper countries but Bermuda isn’t.
Perhaps Karla should have phrased it more precisely - “the number of countries not in the EU is an order of magnitude greater than the number within the EU.”
Would an order of magnitude not be 270? 27 -> 270?

19, 27, 88 are of order of magnitude 1
131, 205, 870 are of order of magnitude 2
The order of magnitude is the integer part (by truncation) of the base 10 logarithm of the number.
