I don't think they're confusing anything. If we use your numbers, then 180GW of solar is less than 5% of energy needs, and that is increasing at less than half a percent annually.

At that rate, decarbonizing by replacing a meaningful amount of the other 95% with solar will not happen in our lifetimes.

Electrifying everything makes about 75% of that energy demand unnecessary as it was waste or avoidable inefficiencies of fossil fuels.
