Can just anyone use the Force?

So in the earlier episodes of Ahsoka, the eons-old Jedi trainer, Huyang, calls Sabine pretty much the worst Jedi student ever. And she herself admits how she can’t really feel the Force. Sure, we also see her working on that fairly regularly, but in the finale, she’s finally able to fully use the Force, grabbing her lightsaber and pushing Ezra onto Thrawn’s Star Destroyer.
That journey makes us wonder if anyone can teach themselves to use the Force or if Sabine had that ability, it was buried deep, deep down—but either way, it opens up Star Wars’ storytelling opportunities when it comes to approaching the Force, Jedi, and Sith, and more crucially what those titles mean beyond the dichotomies already explored in the movies and shows so far.
