Yes, you are right because <meta name="robots" content=""> is required if you want your page not to be indexed in the search engines databasae and want to prevent it to be shown in serps (search engine results pages) by the SE, means you do not want your visitors to be landed on your website through a particular page.
For example, you have a printer friendly pages on your website, which have same content on it like your regular website page and you don't want the printer friendly page to be indexed to prevent duplicity on your website content,
Cheers,
