You state this as fact without providing a dataset to back it. I think
this is not true at all.

It depends on how you define "success".
I would consider people like Linus and Dwayne Richard Hipp and TBL to
be among the most successful people on the planet, and they write
quite a lot.
Do you call people who capture then give away a billion dollars the
most successful? I don't. To me the most successful are the ones who
create billions in wealth and capture just a tiny fraction--enough to
support their family and friends and live a good life.
