More likely =/= guaranteed. Generally when learning a new language you do indeed learn how to read/write it. However that isn't always the case. If you only have conversations with friends that speak a different language how will you learn to write that language? Especially if their alphabet is different from your own.

Here's an example.

It also goes the other way, sometimes people can read/write foreign languages but are unable to speak it.

To say that there are no people that can speak but can't read a second language (in this case, English) is just plainly wrong.

Wasn't the initial commenter, no need to be a dick

There are people that speak English natively but are functionally (or literally) illiterate so yes.
