In order to open office docs in the browser you must have an office online server 2016. Can you verify that it is installed on your farm? https://docs.microsoft.com/en-us/officeonlineserver/deploy-office-online-server

  • I don't have office online server 2016 installed.

I agree with Kasper, you need to install Office Online Server(OOS) for SharePoint 2016 to open office files in the browser. You could refer to this article to configure OOS for SharePoint 2016:
