"but also every language" or "but also any language"; either are fine within this sentence. However the sentence itself is a little awkward. I would say: "Learning English requires patience; the same as any language." We would say "Everybody knows that." or "Everyone knows that." But probably not "Anybody knows that." In bowling you want to knock every pin down (get them all). This is very different than knocking any pin down. If you knock them all down (every pin) you get the most points. If you knock any pin down (any single one) you only get one point. Here is how you could use anybody. "Does anybody want some juice?" Who are the individuals that want juice? Everybody: "Does everybody want juice?" This is used commonly, but it's kind of an awkward sentence. It would be used when the general assumption is that indeed every single person wants juice, but perhaps a few people don't; or maybe no one does and the assumption is wrong.
