Earlier quoted context omitted.
So.. no but actually yes?
I mean, Japanese isn't a Romance (i.e. Latin-derived) language, but the word "pan" is a loan word from one.
Similarly tamatar in Hindi isn't like tomato (resp. tomate, etc.) because of some Proto-Indo-European root, it's just a devanagari approximation of the Portuguese.
I assume the intent in asking 'are they all romance languages' is 'do they all get it from Latin', to which the answer is certainly yes even if the language as a whole is mainly not.
