What exactly happens on a gas planet and if they aren’t able to be walked on, then why are they considered “planets”?

The IAU (International Astronomical Union) has made a clearer definition for what a planet is.
They said: “A planet is a celestial body inside the Solar System that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.”
So Gas Planets still fit into the definition of a planet.
Also, all Gas Planets in our Solar System have a solid core so they aren’t completely made out of Gas but the Gasses are so much more prominent that they are considered Gas Planets.
