Fingerprinting unfortunately uses more than useragent strings. It takes hashes of data in your browser from a javascript context that is not easily masked or removed. For example, it might render a gradient of colors projected onto a curved 3d plane. The specific result of this will create a unique hash for your GPU. They can also approximate your geolocation by abusing the time-to-live information within a TCP packet, which is something you can’t control on the clientside at all. If you TRULY want to avoid tracking by google, you need to block google domains in your hosts file and maybe consider disabling javascript on all sites by default until you trust them. Also don’t use google.
