I am a "newbe" in ham radio.
I think I understand Baluns and ununs. However, I have heard and watched videos regarding transformers.
Can someone explain in simple terms the use and need for transformes? Please remember, this is all new to this 73 year old man.

A transformer can be useful for matching antennas. For instance, the Inverted L is a popular 160 meter antennas. If you don't have much height vertically, the impedance can be very low after the length is adjusted for resonance. One technique is to match the resistive part with a transformer and adjust the length for resonance.
