What is the best way to teach a 6 yr old that losing in sports is a part of learning?

My dad used to make me and my brothers watch live sports matches to demonstrate that in life, there will always be winners and losers. Sometimes at these matches or competitions, the losing teams get participation medals and my dad would say that it's not the winning that's the most important, it's the experience and the fact that you tried. I didn't really agree with that when I was a kid because I loved winning but as I grew older, I realised that is indeed alot of wisdom to what my dad said.
