The number is not low. The only evidence i can provide you is sites like gametracker or game-monitor.
"If there was lots of players playing non steam why would tournaments suddenly drop a popular game? Why did DH Valencia just drop 1.6 when only 3 teams signed up."
Thats probably because nonsteam players are playing only on pub servers and the ones whoever actually bought are the ones who are interested in pro scene and that % isn´t that high either. Nonsteam players don´t give two shits about the pro scene.
If you want some "real facts" you should just download nonsteam cs 1.6 and try out few of the servers you can find in gametracker.
