I'm only basing it on media articles as I don't have access to that data, but if it is mistaken, then it is a mistake shared across multiple sources. See here for a reference (section starting: "la ligne 7 est la mieux desservie"):
Cinq faits à connaître sur le métro parisien Rough translation: "with 60 trains an hour at peak time, line 7 is the best equipped. Line 13, often criticised by public transport users reaches 52 trains an hour. This, however, is a lot more than the 4 trains an hour of line 3b."
And here:
