14 days is still probably enough. There are scattered reports of people staying asymptomatic for longer, but they're hard to confirm (maybe you weren't actually exposed at the start) and certainly very rare. The goal of self-isolation is to severely reduce transmission, not to make it 100% impossible.
People say the risk is low because it's probably good on net if the cases are coming from everywhere; it would indicate that the visible clusters where people die a lot are anomalies, and most cases aren't that bad. The worst case scenario is that containment is impossible but it really hasn't spread widely yet.
