In the video description it says:
"The stories presented on this channel are completely fictional, created solely for entertainment purposes. Any resemblance to real people, events or situations is purely coincidental and does not correspond to reality. These narratives are not intended to portray or allude to real facts, individuals or entities."
Appears to be a mix of synthesized narration and stock imagery/AI pics. I think theses channels just try to rack up views to earn ad revenue; nothing to be taken seriously at all. Although, with the fakes in Rome it can be hard to separate fact from fiction sometimes.
