So I'm curious: How do Diamond players win games where each enemy laner is 4-0 before ten minutes?

Title. What's the strategy? If you play it safe, the enemy is just going to take every objective from the map while you sit back cowering. If you try and play it risky, you're most likely going to die over and over again. I can't see any possible action you could take that could pull back a game like this.
