No one really lives and breathes the game anymore. My Pug team that used to live and breathe 1.6 all day everyday don't even play anymore since cal, and CPL died. Even the Source scene is down the toilet for the most part when CGS died.
Anyway, enough about high level play. Source public play is easy man. Just learn the recoil, the maps, and don't spray. Once you learn the fundamentals of this game, it will transfer into any FPS you every play. While source is easier than 1.6, I think it's harder than any game that's out today simply because there's more teamwork involved than lolcod, and a lot more recoil is present. There's other things that create the skill gap, but I won't talk about that.
I think you are really overestimating the level that most of the people who play source now are at.
