Not really. Who is to say what "deep into photography" means. Photography gear is just a set of tools to produce your pictures. If you shoot portraits and DOF control is important you might want a fast prime. If you shoot landscapes you might want a zoom that is super sharp in the corners stopped down. You don't have to be a pro to have a need..., but for some of the gear you have to have a decent size wallet.
I do agree you need to know how to use these "tools" to get the best results.
Again, I am sorry to say....but if I think that I need for 50L or 85L or something similar, I should probably know how to get the maximum of it and whether these are the lenses I really need. As long as your skills and experience...also talent dictate the need for a gear, it is all great.
