title: Youtube Data Api has commentCount field and is this the number of comments on channel?
body: <p>I'm using Youtube Data Api v3 and there is a field called commentsCount in statistics section, I wanted to know if this is the comments for made by different users on a channel or is the comments made by the channel user on several videos.</p>
  
  <p>for example if I send a HTTP request for Channel 4 on Demand which has lots of comments made by users, I only get </p>
  
  <pre><code>GET https://www.googleapis.com/youtube/v3/channels?part=statistics&amp;forUsername=4oD&amp;key={YOUR_API_KEY}
  </code></pre>
  
  <p>HTTP Response</p>
