This assumption is not correct. For example, if you do not plan to typeset say computer code, then obviously you don't need to set \ttfamily. In addition, some people, like me, for normal texts use \sffamily only for captions, but others use the same font for captions and the rest of the text. In my experience, people use sans-serif fonts for posters, slides, etc.
