If this assertion is based on the Pew "News Use Across Social Media Platforms 2017" (http://www.journalism.org/2017/09/07/news-use-across-social-media-platforms-2017/) please note the question asked in the survey reads:

"Do you ever get news or news headlines on any of the following sites? By news we mean information about events and issues that involve more than just your friends or family."

Do you ever... I'm surprised the figure wasn't higher.
