No. Igneous rock is simply the solid substance left when magma or lava hardens, above ground or below ground.

When magma cools you get intrusive igneous rock. Think of other ig words you know. Ignite, ignition they all mean heat. Igneous rocks are formed from rocks that have been heated so much they melt. When they cool they make new, igneous, rocks. If it's magma that cools that means it's still under the earth's crust so the igneous rock is intrusive. If it's lava that cools after flowing down a volcano it's an extrusive igneous rock that's formed.
