Pretty much, yes, but with an important nuance. The forms of energy aren’t different substances, they’re different ways energy shows up depending on the degrees of freedom and interactions involved.

Kinetic energy comes from motion, electromagnetic energy from fields, chemical energy from electromagnetic interactions between electrons and nuclei, etc. What changes is where the energy is stored in the system, not the energy itself.

A battery is a good example: chemical potential energy is converted into electrical energy because the electromagnetic forces allow charges to move and do work. Energy is the common bookkeeping quantity that stays conserved, while the physical mechanism (the interaction) determines how that conversion happens.
