But if it's 10k ball bearing balls in there, that gives a quite bad ball bearing on average. I've never seen a ball bearing with 3 or less balls in reality.

I guess they used Matt's estimate in the title. Even though Steve says he used a pack of 10k steel balls.

Don't most common bearings have 7-10?

The small ones which have about the ball size in the video usually do. There is far more for industrial equipment like cranes, they also have larger balls.
