Got a source for that? It's easy to find positivity rates for all tests, but not just for those symptomatic.
The best I can find is figure 11a in

which shows that the positivity rate increases significantly with age. (And that's of people with any respiratory or flu-like infection, not just those COVID symptomatic)
