Are sharks older than trees?

Sharks are older than trees. Shark-like fish appear about 450 million years ago; the first trees (Archaeopteris) about 385 million years ago.

Context

Yes, by tens of millions of years. Shark-like fish appear in the fossil record about 450 million years ago. The first trees, Archaeopteris, appear about 385 million years ago.

So sharks were swimming for roughly 65 million years before anything tall and woody grew on land. They have outlasted several mass extinctions, which is why the same basic body plan is still in the water.
