Not all, just 2277 + buyables/easy ones, but still well north of 20k hours (including rs2, so not just since 2013) all told. If it actually were 200m all I'd probably feel differently.
And no, not really.
One, it was a lot of fun. I guess I should clarify that I spent much of that playtime doing pvp of one sort or another and the stats were almost incidental. Mastery of one thing has always been more attractive than spreading time around a bunch of different games, and I have a lot of fond memories of what it was like to play that game at a high level and still have good friends from that time. So, from that angle I don't consider the time wasted any more than I'd consider time spent relaxing, playing any other games or reading a good book wasted. I was never a NEET and didn't really push it beyond what I'd call fairly typical entertainment hours per week, but those hours were just concentrated on this one thing over a long timeframe, and that adds up - especially when both leisure and competitive goals are satisfied by different aspects of the same thing. More a case of being unusually efficient in using my spare/entertainment time than of reshaping my life around it.
On that note, you develop some pretty intense split focus abilities regularly playing multiple accounts at once and/or doing high-intensity skilling. A lot of those hours were actually me, in some kind of zen robot state, bashing out actions while paying almost full attention to reading or watching something else. Read an awful lot of books while grinding, worked on my language, got some good treadmill/powerlifting time, that sort of stuff. I find that I'm more relaxed and creative when doing some kind of physical activity like running, and that same dynamic felt true of skilling. When not multilogging, skilling can be very meditative and relaxing. Something about having a task that takes some but not a ton of attention is just nice.
