Why Am I losing? Gold V Zero LP

I carry most my games on Talon. And the games I lose I consistently have the highest kda, most gold on the team, least deaths on the team, and most damage on the team dealt to champions. Ive started ramping up my warding to where I will try to buy a vision ward anytime I get the chance and have the extra gold. But it doesn't seem to affect the game. Most the games I feel like im playing against bots (in ranked) and have no problem getting incredibly fed and outskilling my lane opponent. I would say I'm not just slightly better than people who are my rating my **significantly ** better. I can't for the life of me understand why I am losing.
