A better way would be to compare the size of Stack Exchange boards at https://stackexchange.com/sites . It's not perfect but it's as good as it can get. Stack Overflow has 26 million users. Woodworking has 17 thousand. A fraction.
Further still, not every woodworker will use a belt sander. It's used for a specific purpose (large flat surfaces) and it's not a beginner's tool. So the fraction gets smaller. I'd say the assumption stands.
If you have better data that shows an overlap between those in the technical field and those that do woodworking with highly specialized tools, I'm all ears; I'm willing to be convinced otherwise.
In the meantime, here's another anecdote for you - I do woodworking (and gardening and constructions) and I don't own a belt sander.
