Your answer to the question should be no unless you have applied before for any kind of visa, be it study, visit, business or PR for that matter.
You would only be provided with the UCI no if you have submitted an application for any kind of visa. You would be give your UCI no regardless of the outcome. In my case i submitted my application for PR couple of time in 2014, but it didn't get processed on both occasions for various reasons. Hence, despite submitting my documents, i didn't receive UCI no, neither my processing fees were deducted on either occasions. By creating your EE profile, that doesn't mean you have applied before. Hope that clarifies things. Good day
