What this video covers
A navigation drawer hides a menu off-screen behind an icon - usually the three-line "hamburger" - and slides it in when tapped. It buys back screen space by putting navigation out of sight, which is its strength on a small screen and its weakness everywhere there was room to show the links instead.
Behind the hamburger, the links existed but did nothing until you went looking - out of sight, out of mind. Shown in a bar, the same links advertised themselves and the main one was a single tap away. The drawer didn't remove the navigation; it removed people's awareness of it.
