I'd agree that it doesn't matter much within a certain band of distros. Fedora vs. Ubuntu, for a new user without opinions about things like Flatpack or rpm vs. dpkg, doesn't matter much, sure, I agree. Throw in Slackware, Gentoo, Void, and Arch, and now it kinda does matter which you choose. Even Debian, since your software will be farther behind current releases and its preferences about things like non-free software are likely to be something you notice and have to deal with, one way or another.

But, among the small set of relatively user-friendly distros, sure, it doesn't actually matter that much. A generous reading would take that meaning from it, I think.
