A suggestion as to the way forward at Unreal

Hello, I am a young boy who is looking to delve deeper into some of the areas supported by Unreal so that I can become a freelancer on this platform, without having prior knowledge. But there are many options to delve into, such as in the branches of 3D or in blueprints, for example. That said, I would like to know which of the follow-ups would be better to focus on this platform, seeking the one who has the best of opportunities.
Thank you for your help and attention.
