That chap is a very very good YouTube science explainer, I like him. And this point is dead right, think about the fact that we can see photons of light that have been travelling towards us for 13 odd billion years and they haven't been absorbed by anything in-between. It's very empty and big out there. Also think about the Cosmic Microwave Background Radiation which was released during the recombination epoch about 300,000 years after the big bang, those photons are the oldest in the universe and they are everywhere just arriving at our detectors now after almost all of the lifetime if the universe There's nothing special about those photons just arriving now as they have been just arriving now for the whole life of the universe, the ones we see at any moment are just infinitesimally colder (longer wavelength) than the ones we experienced a moment ago, they are all around us all the time just turn on an old fashioned TV set in the old days and you could see them they are the static white noise on the screen, didn't hit anything for all that time until they hit your TV aerial. The interesting thing is that photons don't experience time, from the photon's viewpoint it arrives at your aerial at the exact same moment it was created all that space in-between is meaningless to the photon.
Indeed, pretty much all 'change' that we as individuals experience is communicated via the electromagnetic field and that means photons, all of chemistry pretty much electromagnetics, we also experience a lot of change via gravity but from an individual viewpoint light and heat are overwhelmingly the way we experience the world, even sound waves are a result of the electromagnetic field of atoms interacting to create the slow sound waves. So yeah photons are special and were first theorised by Einstein in his special publication year of 1905, a total of four groundbreaking papers one of which quantised light and laid the foundation of quantum theory, a theory he never really liked.
