It really depends where they live, while they do English at school it doesn't mean they are any good at it - I did French at school, and am useless at it
My daughter lives in the Netherlands now, and 'generally' English is widely spoken - particularly in Amsterdam. However, where she lives is close to the German boarder, so their second language tends to be German rather than English - I went to a small Radio Museum there, and the guy who runs it doesn't speak any English at all, and was very excited to have an English visitor.
My daughter is currently leaning Dutch, and due to take her exam later this year - essentially a high school Dutch qualification.
Her brother-in-law failed his English at school, and this was limiting his work potential, he works in a clothing store and you can't get promoted with out having the high school English qualification. Melissa and her Husband helped him with his English, and he retook it and passed OK - he now manages the store.
When we popped in to Germany last year we didn't find much English been spoken - but again, it's not the sort of area where you're likely to.
