Visibility of documents, spreadsheets, and presentations published to the web
When you publish Google Docs, Sheets, or Slides to the web, anyone who has the URL to your publication can view them no matter what visibility option you’ve chosen – private, anyone with the link, or public.
Visibility options don’t apply to a publication because the publication isn’t the original item but a separate webpage version. In other words, by publishing Google Docs, Sheets, or Slides, you’re creating a copy of them that’s a unique webpage with its own public URL.

Private Google Docs, Sheets, and Slides published to the web
Not sure how a file with a “private” visibility option can be published to the web? Here's an example that may help:
You’re working on an event flyer in Google Docs that’s set to the “private” visibility option and shared only with a small committee of people. Just before the event, you publish your document to the web and post a link to your now published flyer on a variety of websites. Anyone who comes across the link can visit the published web version; however, only committee members you’ve invited to view or edit the private document will have access to the original.
