Affiliate marketing as a JOB? and where can I learn it FREE?

I started reading about affiliate marketing and am curious if it really can be a full time
JOB.
Also I’d like to know where I can learn it for free without needing to pay some fee to someone who wants to sell me on info that may or may not work.

Any opinions?
Please answer and not just give me links with affialite id’s etc.

Can this be a real job?
Also where can a person learn for free even just a good basics course with no fees to pay?

Thanks for taking the time to answer

IF THE ANSWERS ARE GOOD PLEASE _DO_ INCLUDE THE AFFILIATE LINKS… But pls actually answer the question as well, y’know
