What Really Makes You Better at Jujitsu?

The two things that matter for getting good at jujitsu are understanding and repetition. If you can't explain side control, what the goal of side control is in a sentence to me, I don't think you know it. To win on top, you understand what pinning actually is. Pinning is keeping the person flat. And pretty much every escape that you see from a bad position starts with get on your side. You will win way more jiu-jitsu by doing positional sparring.
