That depends on what you mean by "learn GeoAnalytics". The map object in Qlik Sense June 2018 is a basic version of the GeoAnalytics map object. It does not have all the functionality (yet) of the GeoAnalytics Base map object. And GeoAnalytics Base and GeoAnalytics Enterprice also come with a GeoAnalytics Connector that can do a lot more manipulation of geo data that Qlik Sense can do when loading data into the Qlik Sense app.
The map icon in your screenshot is for the standard in Qlik Sense included map object. Nothing needs to be installed to use it.
