The custom permalink field on the settings->permalink screen only applies to Posts. Not to Pages.
WordPress Pages always live at the “top” of the URL tree. /about /whatever /etc. Posts live wherever the custom permalink string defines them to be.
So, in your case, your permalinks custom structure would be “/news/%postname%/” and would not affect your Pages permalinks of “/about” and “/resources”.
For instance, to put all Posts under the sub-directory “/blog”, your permalinks custom structure would be “/blog/%postname%/”.
