I agree it's intimidating. I think the way to counter that is good player aids. If you have a really well designed reference in front of each player, then the teach is often "see that second line, well this is how that works". Also the teacher should read the rules ahead of time, so they can can summarize or go in more details depending on the comprehension of players.

Those videos often gloss over a lot of specific details (e.g. round-up or round-down) and thats fine to gloss over in teaching also. If the first game runs smooth and gives the game experience, they're more likely to play again than if you have to stop and dig through reference multiple times. You can always look it up after so you do the second game more correctly.
