Here's why:
* Hyperbole: A hyperbole is an exaggeration used for emphasis or humor.
* Literal Meaning: The sentence could be interpreted literally. It's possible that the father left all his money to his son in a will, or gave it to him during his lifetime.
For the sentence to be a hyperbole, it would need to be exaggerated. For example:
* "He gave his son all the money in the world."
* "His son inherited an ocean of money from him."
These examples use exaggeration to emphasize the amount of money involved, making them hyperboles.
