No. I think that in the context, 600k likes is low engagement.
We are speaking about 2-3 orders of magnitude difference.
For comparison, MKBHD video [1], 1.2 orders of magnitude difference between views and likes; Adam's video [2], 1.4 orders; 40 minute long video essay on House Md [3] (1.5M views with subscriber count of 0.15M) , 1.7 orders of magnitude.
Carlson's engagement has 2.17 orders of magnitude difference, while being as long as [1], longer than [2], and far shorter than [3].
All of the videos above are supposed to be far less "entertaining" and are expected to have far less engagement value, yet outperformed Carlson's thing.
