A 'bad player' isn't someone who comes in unprepared, it's someone who can't react or learn or engage in what might be called 'rational behaviour' in the game environment sense. For instance, in the XIV sense, a bad player would be an individual who routinely gets hit by standard red-zone AoE, or doesn't figure out Ifrit's plume rotation within the first few runs, or doesn't understand the most basic elements of tanking despite reaching level 50 on a Paladin.
A 'good player' is someone who doesn't embody these unfortunate traits. They learn quickly, adapt rationally, and while they make mistakes, they don't generally make the same mistake twice. Such a player will also generally recognize when their gear is insufficient for a particular challenge, which is why they are rarely seen engaging Garuda with a level 45 weapon and full AF.
TL;DR - Both good and bad players can do their homework, or not do their homework. A good player will quickly learn whether they have or haven't researched the activity in question, while a bad player will fail to be proficient whether they have done the homework or not.
PS - This discussion, from my perspective, is completely separate from the question of whether or not someone is enjoyable to adventure with. While I generally prefer adventuring with good players, there are plenty of talented jerks, and plenty of wonderful people with dubious skill.
