Technically, silicone grease is a sealant. Unlike some alternative sealants, it does not have adhesive properties in the sense of gluing things together. It is also weak if not captured, e.g. by threads. Both binding and non-binding possibilities are consistent with the definition of sealant so it is normally best to describe whether one is merely seeking to impede the flow of moisture, or to bind stuff together (while impeding moisture), or simply to make things easier to move or take apart.

Hmmm... the last time I had this conversation with some pros I left understanding that silicone is simply a water/ink repellant but not sealant in the technical sense

Look up definitions, and consider the distinctions I outlined.

 

Only poles of similar charge repel. Silicone grease is merely hydrophobic, which is to say it excludes water molecules. So do well-fitted threads without any sealant whatsoever, if they are a tight fit. Glues and rosins not only have sealing properties but additionally binding properties (glues rather much so). Then comes the question of capability of something to fill gaps, or what is its self-binding strength to hold under pressure in gaps of different sizes. Also consider what works with what materials.

I see what youre saying, it does make sense
