Is it worth learning Wyckoff

I’m just starting to learn technical trading in depth. Have fundamental concepts. Is it worth Wyckoff trading since the logical events are mainly volume based and from what I’ve read there’s much more volume manipulation than in his times.

I’m wondering what the best approach is to focus on learning. I know that major skill is experience but the concepts you learn matter a lot too. So wondering if Wyckoff + ICT is a good learning path.

Also how realistic is it to be a fulltime trader. What would you say is a realistic ROI long term
