To be fair, it's pretty outdated terminology.

It comes from an era when computers were so genuinely slow that doing almost anything - even using page layout like Pagemaker, or setting up just a single track song in a DAW, had tons of render lag. Even spreadsheets would take significant amounts of crunch time to run their calcs, in the very early days. This meant that most work done on computers, with anything larger than a "toy/hello-world" dataset, was going to be painfully slow. That's why they called it "professional" - because you were actually using datasets large enough to burden the beast. Actually balancing a whole company's finances with a spreadsheet, rather than tallying up a little 10-item list.

I want to emphasize that "majoritarian" aspect of it - it wasn't just a few specific kinds, it was a majority of ALL kinds of work.

And that's changed.

We're now at a point where only a tiny minority of tasks done on computers actually have throughput limits based on the computer rather than the operator.
