You should :require the namespaces, not try to :import things. (ns your.namespace (:require [next.jdbc :as jdbc]))
I suggest you start off by working through https://cljdoc.org/d/seancorfield/next.jdbc/1.0.9/doc/getting-started The ds binding that you have will satisfy this check (instance? javax.sql.DataSource ds) -- because it is an instance of that Java interface. It sounds like you have quite a few misconceptions about using the library (and perhaps using Clojure in general?) so I highly recommend joining the Clojurians Slack http://clojurians.net and https://clojurians.slack.com where you can ask real time questions in the #beginners channel and next.jdbc-specific questions in the #sql channel.
