You should only study endgames if you want to stop being a beginner. If you enjoy being a beginner and losing to everybody, then endgame study is something you want to avoid.
This is ridiculous, beginners lose the vast majority of their games in the openings and middlegames. It doesnt matter how good you play endings if you fall into an opening trap or get mated in the middlegame. Outside the most basic endings beginners shouldnt spend much time on endings until they are actually reaching endings without already being lost.
