electricity is't the majority of the energy consumed in nearly any country.
it's a easy way to keep confusing less vigilant people by calling electricity as energy.
Just call things the way they are.
You're right; 2/3 of worldwide energy is actually waste heat.

Here's the chart from 2007: Waste heat / losses are in the top right, although it doesn't show the transport sector losses which are higher than for coal generation.
What this means is that when we fully electrify all sectors, by using renewable energy such as wind and solar, our total energy generation capacity will only need to be about 1/3 to 1/4 of what we currently produce today to fulfill our current energy needs. That's huge.
Correct me if I'm wrong, but electrifying a process doesn't automatically make it not produce waste heat, right?
No but electric motors and heat pumps are much more efficient so electfication helps reduce waste heat
