Sure, but you are comparing statistics for an entire country to a specific incident. Of course there's a non-0 risk, but when it's about traffic and safety it's about acceptable, not complete elimination of risk.

It's still illegal in the Netherlands to bike drunk. I'm sure this would be aggressively enforced in cities like Groningen if statistically there were major safety issues Thursdays and Friday nights with drunk cyclists, but this is not the case.

Not to say that your friend shouldn't have walked instead though. Drunkness is also a sliding scale. Luckily with cyclists the chances are way lower of murdering others.
