i am currently studying from a book and it says that not all gas molecules energy have the same amount of kinetic energy. Because of that, the term average kinetic energy is used. Can someone explain this?

One gas molecule may have more kinetic energy than another given gas molecule of the same element, and so when talking about the kinetic energy of the whole gas which is comprised of many molecules, the term average kinetic energy is used.

The definition of temperature is "the average kinetic energy of the particles" or in other words, how much they are moving, on the average.

Kinetic energy, KE= 1/2 mv^2, 1/2 mass X velocity squared

The kinetic energy of a particular particle or gas molecule would be determined by its mass and velocity.  The average is the temperature of the sample.
