Why should high card show a profit?

Aren't there times when you call the flop and turn on a draw and the river goes check/check, with something like 6 high? Isn't this considered "high card"?

Or you bet the turn in position knowing they could easily be peeling the flop with overs; once they call the turn you know your beat , so you check the river?

I don't understand why high card should show a profit.
