I don't watch videos but I clicked on the links to the sources.
The ICCT report shows that hybrid passenger vehicles produce about 20% less emissions than a similar gasoline vehicle. That still seems significant, even if there are even lower emissions available.
And that seems obviously true, the way that hybrids tend to use lower power, higher efficiency internal combustion engines than similarly sized full gasoline vehicles, and recapture some portion of the energy that would otherwise be wasted.
