[D] Probabilistic Graphical Models

So I'm in a middle of confusion whether to study Probabilistic Graphical Models.

Currently the next 3 domains I want to explore are

Artificial intelligence ( whose course I'll take in my college coming sem) also the cs 221 Stanford course

Causal Inference ( Whose SOP I've got for next sem

Generative AI

Would i need probabilistic graphical models knowlege for these topics .

Thanks
