Playing a lot is not the same as knowing it
This is the gap the quiz is built around. A strong player picks up a weapon and knows within a second whether it suits the fight, without ever having read a stat. They can tell two maps apart from a single rooftop and could not tell you which is bigger by area.
Recognition and recall are different skills, and mobile battle royale rewards the first almost exclusively. Being asked to convert that instinct into a named answer is unfamiliar, and it is why competent players lose points here.
