I am not sure either follows. But it depends how we even define "older languages", especially considering differences between python 3 and 2, are they the same age (based on the original python release) or are they treated for their respective release version?

Just taking some simple release dates [1] or wikipedia I found:

Ages of "Yes" group: 49, 36, 22, 26, 26, 12, 31

Ages of "No" group: 11, 14, 33, 7, 32, 45, 26, 34, 21

Averages: Yes 28.85, No 24.78

With the ambiguity around what "age" even means for the language here (e.g., counting the age of node.js or python) it is probably meaningless, but it seems well mixed independent of age.
