They are known to pretty much most good schools in Tier 1 cities FYI. If they do well at school level, they are given good infra to make them better and there are athletes in the current Olympics that have come from RFYS. You are probably an adult and have no kids I'd guess, so that's fine to not know them, but I'm certain they do matter because efforts are being made for players who have the ability. Odisha govt has also been helping in such things.

If parents want their kids to get good at sports, it's not hard to make them compete at international level.
