Unfortunately, this is definitely not true. Let's take basketball as an example. It turns out that around $$$1$$$ in $$$6$$$ Americans over $$$7$$$ feet tall have been in the $$$NBA$$$, which contains around $$$400$$$ people (so around $$$1$$$ in $$$1$$$ million normal Americans are in the $$$NBA$$$). So if you are over $$$7$$$ feet tall, you already have an extremely good chance of making it to the $$$NBA$$$, especially when you consider that a lot of those $$$7$$$-footers might not even want to play basketball. Basically, if you are $$$7$$$ feet tall, you just have to practice a little bit and you're in. But there has never been a midget in the $$$NBA$$$, and surely there has been a midget with a lot more consistency than the average $$$7$$$-footer.

but luck and cheating always have the last word (an allusion to being important)
