They were questioning only 190 participants, which doesn't seem very representative.

  190 participants, properly selected, can actually give extremely trustworthy results to a fair confidence interval. Sample size isn't everything...

    Would you consider 190 participants that participated by clicking on an ad to be properly selected?

      Depends how well the ad was targeted and how well quotas were set and screened for. There's a few good ways to attract survey respondents through ads, and a whole lot of bad ways.
