Why Google still use my localisation when I have disabled all location services? When I use google.com (usually I work with duckduckgo instead, because of privacy policy) on my Phone (in web browser), it shows me my city and country on the bottom of the page.

I have disabled everything in Settings -> Location services. What else do I have to do in order to disable any possibilities of sending my location to Google Search and other websites?

I Use Android 4.
The system setting and the browser setting for location use different systems. When you disabled those settings in system settings, you disabled Google Apps (and other apps) from using your location, using your hardware.

However the browser differs in that while you use a webpage, the web server can use your IP address to locate you (using IP-address-based geolocation). This does not have anything to do with system settings. The browser does not prompt you about this.  Indeed, once you connect to their servers, there is no way to prevent their servers doing IP-based geolocation, as their server can see your IP address and draw inferences about your location on its own.
