No. It's not. It's a neutral signal. It can't tell you anything either way. Even the github profile isn't a strong positive signal, it's a weak signal. But that's ok. That's really what we're looking for: a lot of weak positive signals. So that person had a github profile. Everything else could either be a neutral or negative signal. Compare that with someone without a github, but has every other positive signal you could ask for. I'd take non-github person over github person every single time.
