I don't think it's hyperbole as much as it is just regular ordinary everyday slang.
"I have a hundred things to do today" doesn't mean that a person has 100 things on their list for that day.
Outside of tech bubbles, people talk like that.
It's like how the Bible uses the number 40 as a shortcut for any very large number. 40 years in the desert, 40 days of rain, etc… It's not a calendar, it's an illustrative euphemism.
That’s the hyperbole the parent was pointing out.
