True, but PE might have had a positive effect on many people other than you, both physically and in other ways, so at the very least it's more effective than doing nothing.
That said, I do hope of course that they offer more variety than they often do in high school. I was pretty lucky with my high school and definitely benefitted from being exposed to sports that I still engage in occasionally (rugby and ice skating).
I think the real problem is exposure. I don't like running, soccer, or football -- so my years in PE were generally a waste. There are physical hobbies I enjoy but the odds of being exposed to them in high school were improbably slim.
