Must

It's possible.

Possibly, yes. If you say that, it means that you have some information that tells you something is true, but you're not sure.

for example, if you see a woman with a ticket going to the airport, you would say "she must want to go there". However if you knew certainly that she was going to the airport, you would just say "she wants to go there"

Is this clear-cut? Not for me.

It will be clear in context.
