The phrase "people helped" doesn't concisely convey what you described above because it appears without context. If you change the order of the stats, it may be a bit less ambiguous. Try switching the order to: "60 questions, 195 answers, 207k people helped." That's a bit clearer. 

But this is about **"reach"**. You should say their *contributions* have reached 207,000 people.

If you add a bit more context to the stats (below), it will also be a bit easier to understand. The presentation should look something like this:


![Profile: people helped](https://i.sstatic.net/fWVvC.png)

If you want to stick to that *"helped {x} people"* motif (or if the example above is too long), I have a few other versions I was playing with. Maybe you can mix and match:

> These posts have helped  
> #~207,000
> people searching this site

Or something that works when viewed in the context of the screencap above:

> Has helped
> #~207,000
> people through this site.

Hopefully between them you have something that better conveys the sentiment you are driving towards.
