Correct, but it is the largest data set from screen reader users available.

This is not correct. 89.2% of respondents to the survey that is linked
here reported using a screen reader due to a disability. When there
are notable differences in responses between respondents with and
without disabilities, we note these, but most of the time the
responses generally align. In other words, the 10.8% of respondents
that don't have a disability do not skew the reported data in
significant ways.

Your suspicion is generally incorrect. 64.7% of respondents with
disabilities use NVDA compared to 69.3% of respondents without
disabilities. So usage is slightly higher among those without
disabilities, but these are so few in number that this skews the
overall NVDA usage percentage by only .2%.

We'll be publishing results from our most recent survey in the next week or so.
