This is true
lettuce not even take into account physiological extremes, let's be veridical
a normal diet will be of mixed composition to some degree
the dietary fat is by far the only nutrient that'll be stored as body fat
Proteins are just highly inefficient anyway. It's a more metabolically demanding process. There's no reason to choose to store the protein as fat as opposed to that lipid itself. Now, to satiate your curiosity I'll very briefly consider the extreme: yes, protein can be stored as fat and will be permitting there's a deficit in your intake of lipids/CHOs. It's unlikely that would ever happen though, as protein is highly satiating. It's not at all a realistic scenario.
CHOs have a higher proclivity to store as bf, but they still won't be under typical mixed diet conditions. As stated in the video, they can be hepatically converted via de novo lipognesis (DNL) into fat, thereby easily being stored, but it usually doesn't occur. There was one study IIRC that showed like up to 8g of fat/day produced via DNL when overfeeding and including like 300-350g of CHO. So not very significant lol. If you restrict fats severely and grossly overeat on CHOs though it will readily occur. Instead of being converted, CHOs impact lipid storage & oxidation directly. Causes the preferential utilization of CHOs for energy more than would normally, retaining the fat stores.

I get what you're saying but you could have said that in 2 lines
