Normally I'd be right there with you. However, this is Jerry Miculek. He holds 20 verified world records with various guns and 7 world championships in IPSC shooting. He has absolutely nothing to prove to you or me. So, I believe it and you should too.I don't believe this video.
You're correct about the two factors, but a little off with the second parenthetical description.The way I've seen it described, there are two different factors involved in how a gun hits what it's aimed at: precision (which controls the gun's innate consistency when used) and accuracy (which addresses how the gun and the shooter work together.)
In any measurement system you have precision and accuracy. Precision is how well a stated system can repeat the same measurement and get the same result. In the case of a gun, it's how small a group can it shoot when all human error is removed. Precision is not directly related to the goal or center of the target.
Accuracy is how close to the goal or intended target can you get. This is also a function of the gun itself. If the sights are misaligned, then the gun is not going to be accurate. With any gun it will only be accurate at one distance. This is load dependent.
Now, you have the precision and accuracy of the gun and then you have the precision and accuracy of the shooter. Two related, but different measurements.
Take a look at these pictures:

This is just bad shooting. You can't tell anything from this target. The shots are all over the place.

With this one we start to learn something. If the shooter is standing and unsupported, we know they are doing things correctly, but need to work on their shot process. If this is from a rest, we know the sights are probably aligned properly, but the gun is not very repeatable.

With this one we can see a lot. If the shooter is standing and unsupported, they have something wrong with their technique. Whatever they're doing, they're doing it the same every time. If shooting from a rest, the sights are probably off. But the gun is very repeatable.

Everything is going right here. If the shooter is standing and unsupported, they are better than 90% of the shooters out there. If shooting from a rest, this gun could be better, but it's now down to refining the load, maybe a match barrel or something like that.
When it comes to shooting we must also define the intended use. Considering the last pic, if this was shot at 3 yards and it's a bullseye gun, shot from a rest, this is not very good. However, if it's a defensive gun, shot from standing and unsupported, this is great. If it's done under time pressure, this is amazing.
So, it all depends on what's important. Hitting a target at 200 yards with a snubby revolver, fired double action and only getting one out of 5 is good shooting. It's plenty precise and accurate for that type of gun.
I could go on, but I'll leave it here for the moment.
