That seems a little harsh. I'm sure I've had at least that many bike crashes with half of them occurring during my first year of riding and most of the rest over the following few years. Only one was serious (at age 10) and none had long-term consequences. Fortunately as my bones have hardened over the years my rate of crashing has gone way down. Only one of my crashes was the result of a mechanical failure (broken steerer tube). Several were the primary fault of others, but could probably still have been avoided.
