Is the finite difference method necessary for cfd?

Hello everybody first post here, I am learning cfd through a self-learning approach since my university did not offer an undergrad cfd course. I have just finished learning my first cfd course based on FDM from YouTube provided by the university of Boston and instructed by prof Lorena barba. And as a cfd novice I am curious about one thing. I have noticed that most introduction courses to cfd are based on FDM, but I wonder why is that? why aren't introduction cfd courses based on FVM as I guess it can do more(works with structured and unstructured meshes,results in a conservative form of the numerical schemes and many other benefits that I am not aware of).
