No one can tell you if you can be a successful freelancer or what you need to do in order to be successful. Being successful is as much about who you are as it is about what you can do. They are not mutually exclusive. For starters.. aiming for "low pay work" is a sure way to NOT be successful.
This is kind of like posting....
"I can play guitar. I know several songs by The Beatles and Eric Clapton. I know all the major and minor scales. I can tune my guitar 5 different ways and know songs for each tuning. I want to be rock star. Can I be a rock star?"
Well, yes you certainly can. However, being successful isn't really in the "what I know" category. There's drive, determination, work ethic, communication, personal interaction, organization, along with a hundred other non-educational factors that go into being a successful freelancer in any field. After all anyone can take courses or learn the educational aspect of any job or career. Being good in that career goes beyond simply knowing the technical aspects.
And there's also luck. Some freelancers will not own up to this one because they want you to think everything is hard work. It is work, but the truth of the matter is there is some luck involved. It's lucky that you get that one job that leads to another that leads to the best client you've ever had. It's lucky that some random person saw the work you did last year and wants to hire you for a job today. It's lucky that your clients continually have more projects for you and like working with you (not all of them will). There's luck in meeting the right people at the right time. There's luck in having the particular skills someone needs at a particular moment.
So yes anyone can be a freelancer..... but not everyone is successful at it. Without knowing you personally it's just the flip of a coin as to whether you would be a good freelancer.
