So looking at the source it sounds like they did an interview with someone from Nintendo France and were told that 7 % of French people own a Switch. Seems like a weird piece of information which is probably why they calculated it to an actual number of people, but that also means there's probably a notable margin of error on that number. Impressive nonetheless.
Also sounds like 51 Worldwide Games did insanely well in France if it outsold Ring Fit, which has been topping their chart often.
