Sure. If it quacks like a duck and walks like a duck, then it must be a duck. But more important to keep your eyes on the price instead of ducks.

This is a disturbing question. Why do you want to know? It is best to mind your own business. But since you ask, we are all magicians because Our Father is Chaos. Any time we interact with Chaos we try to impose our Will upon it. Some do this using ritual, others by starting wars, giving money away, etc…. As Crowley said: The Law is For All.
Having said that, if you are asking because you are looking for a guru or a master, you best make sure that person has some qualifications. By their fruit ye shall know them. As for your relationship with a guru or master: you may not even realize you are in one. That relationship is very subtle and informal. The exchange of knowledge can be summed up as an exchange between friends who don’t realize they are involved in such a relationship. It is a two way street, each teaching and learning from the other. From their eyes, they are simply friends and lovers of Truth. That is the best case scenario in my opinion.
