And why are french fries called french fries? Isn't it more apt to be calling them "potato sticks"?

Easy explanation to it?
The straightforward explanation of the term is that it means potatoes fried in the French sense of the verb "to cook", which can mean either sautéing or deep-grease frying, while its French origin, frire, unambiguously means deep-frying : frites being its past participle used with a plural feminine substantive, as in pommes de terre frites ("deep-fried potatoes").
The more long-winded way?
