Yes, it impacts the standard that you will be taught in schools and hear on the media, as well as what you should use in formal situations. But, outside of the higher registers, it really doesn't impact it at all. People rarely speak the standard as a native language, and we're much more likely to pick up our language from our peer group and parents. This does, of course, change with higher educated people, who are more used to using a higher register [1] of language that more closely follows the standard. Also, not everyone speaks like they write; writing really should be divorced from language when talking about language change and such, as it's generally not indicative of how people talk since they're following set standards that are explicitly learnt, unlike language which is acquired naturally.
