No treally, you're describing a high "click-back" rate. Bounce rate measures a lot more than clicks back to the SERP.
What can mean bounce rate?
- User opens a page of a website and then instantly closes the browser - User clicks back (in this case 90% comes back to google) - User follows a link to a new website (from the current page)
I think out of this 3 factors an high bounce rate website on top of serps is going to sends lot of more traffic to google. (But still I repeat: I don't think google will ever think to reward high bounce website)
