Fact based on what? I don't doubt the kernel claim. There are regular LWN summaries, about what companies contributed to whatever release.

But I have no clue what you're basing your second claim on. There's huge amount of FLOSS programs that work fine, are useful, but don't get much contributions. And I don't know about any studies/overviews on what number of programs say in a Debian distro is a work of passion, and what is created by paid devs.
