I'd say the vast majority of users think "Office suite" == "Google Docs." I don't know the last time I've touched a locally installed office suite whether MS Office or LibreOffice.
Your sample is not representative. Plenty of people still use MS Office. It's not only local install anymore either now that they have an online version.
It's probably fairer to say Google Docs OR Office365--though in my personal experience I see Google a lot more. But how many people are actually installing local copies of office productivity suites? I certainly don't see them when people send documents around.
