Yes, some people go on and on talking about nothing. You'll know you're guilty of that when the top comment in the comment section is, "Click to 4 minutes, 38 seconds to get to the actual how-to part."
Editing can go both ways, of course. If you edit the video down to a short length, there may not be enough time to properly show the hard parts and areas you struggled with.
Some people edit out so much it's like, "Today I'm going to show you how to replace some vacuum hoses. In order to reach the back ones, first we'll need to remove the transmission. (video cuts to the transmission out of the car) And.. it's out."
