Yes there are crappy c# developers. I've also seen some bad ass c#.
The problem is that when you go to hire, you have very little information about just how badass a prospective dev is, unless you've worked with them before. So if you take a random dev out of the C# pool, chances are he'll be worse than a random dev in the Python pool.
That was probably true in 1995. But not today. Python has become the new Pascal/Java. Commonly the intro language in CS, so you have a lot of students who graduate using Python regardless of skill.
If you said Haskell, then probably. Actually C++ maybe more then either, surprisingly.

It seems that wasn't the case even a year ago, though.
