Does having green boogers all of a sudden with no clear runny nose beforehand indicate a sinus infection?

In brief: Not always
You can technically go directly to a sinus infection, without having clear drainage first.
Without getting a culture from your sinuses, it can be challenging to diagnose a sinus infection. Some studies say that you need at least two symptoms to more convincingly diagnose this: green/yellow (purulent) drainage, facial pressure or pain, congestion.

In brief: No
Oftentimes, nasal mucus dries up in the nose and present with a yellowish or greenish color. Still, even if it's thick mucus, it does not suggest a sinus infection without other painful symptoms.
You can get same thick mucus when you have early stage cold..
