To cut Anglophones some slack, quite a lot of people are bilingual by knowing their native language + english because it’s pretty much the de facto international language, especially in Europe. For Anglophones it just happens that their native language is english, so they don’t bother with learning a new one since realistically they don’t need to, whereas for others knowing english is often mandatory for jobs.
Besides that it’s much easier to learn english than any other language because media and culture in english is unavoidable unless you live without internet and TV.
