I don't think that's the case, especially among the younger generations which are largely English speaking and grew up with the internet.
In Germany and as far as I am aware also in France and Spain - all three are among the largest EU countries - the younger generation is hardly largely English-speaking. Only the more educated people (who studied at a university) are typically somewhat confident in their English, and at least in these three countries English is nevertheless only used as a second/"helper" language.
With UK having left the EU, the only EU countries where English is an official language are Ireland and Malta; in both of these countries English is only one of the official languages, not the only one.
