It's worth pointing out that most of the posters who say yes to your question launched their sites many years ago.
I see the same thing everywhere. The answer is yes if you built your site in the early years and bought a domain name based on a valuable keyword.
Those people got established and made good money when the good money was available.
The answer is no if you started recently, or at least very unlikely.
Consider a few facts:
1. Indexed Web pages are growing 70% a year.
2. Domains are growing 30% a year.
3. Internet advertising is growing less than 20% a year, and the rate of growth is slowing.
In other words, page and domain growth is far outpacing ad growth. More sites and pages are competing for fewer ads.
