AC Ammeter
It is clear on the video that the clamp meter is set to read AC Amperes. There does not appear to be a setting on that meter for DC Amperes. This is not uncommon because the method and hardware in the instrument is quite different between AC and DC detection and DC is more costly so cheaper meters often do not include DC Ampere capability.
You can see the selector dial set to 66 A~. That means 66 Amperes AC full range. You can also see AC on the left side of the meter's viewing screen confirming it is set to AC.
When he clamps around the battery cable, the meter isn't lying, it is simply reading the AC component of the current in the wire or ripple and not the DC Amperes. The instrument appears to be working properly. It is an operator error; using the incorrect instrument. citfta explains this in his post.
It would be interesting to know more about these guys and why you appear to trust them yet discredit universities so often, even later in that post.
