I'm a little confused by this, you say you don't know why anyone would believe it, and then outline exactly what I said. There are way less animation jobs than there are animators, leading to extremely nepotistic hiring. You either know one of the big shots currently making a series, or you think and act exactly like one of them, and they hire you for that reason. It's why 90% of animated shows are so similar right now, not just because they're trying to copy one another, but because only people similar to their creators get hired, and go on to make even more shows similar to 90% of what's out there already.
Either way, he doesn't know someone big already, and a quick google search will find his youtube channel mostly dedicated to trashing the industry with special focus trashing the creators usually, guaranteeing no one will ever hire him.
