Yes & No.

Helium Gas is found in air.

However, because it is a very light gas, it is able to escape from Earth's atmosphere, and so it is very rare. The concentration is: 5.2 parts per million in Earth's atmosphere.

There are two "stable" Helium Isotopes, 3He & 4He.

3He is essentially a solar fusion product, and is very rare on Earth.

4He is produced on Earth as a Alpha Nuclear Decay Particle.

The majority of the Helium you use for balloons and etc comes from Oil & Natural Gas wells, and is the 4He Alpha Decay Particle variety.
