Yep

We need to remember the whole thing is based on POWER dissipation
measured in Watts over time. The concept was that you needed a
lower wattage resistor on the primary of a transformer than on the
secondary of the same transformer to dissipate the same amount of
energy.

All tranformers do is trade off volts for amps or vice versa. The
total wattage in cannot be less than the total wattage out.
Otherwise you have perpetual motion machine!
