This is not a way to escape Google, searches on DuckDuckGo will still influence Google suggestions. Despite claiming "no tracking" they still create multiple cookies and while they may not store the data on their own database servers (which is unlikely but would allow them to defend their claim in court) they are certainly selling or giving access to Google. This is the world we live in, the only way to deny Alphabet and the alphabet soup they service (NSA, CIA, FBI etc...) is to not use the internet.
