I'd look at this thread, which contains years of advice to people who asked your question. This advice was good, free, and mostly ignored.
This is only true for strong winning players. Are you already a strong winner with a decent track record at the stakes you want to play as a pro?
Everyone feels that way. Here's the real secret, most of the people who are successful and use this as an explanation are fooling themselves. Consider survivorship bias anytime someone my age tries to explain our success to you based on "wanting it more". For every microsoft (name your rags to riches startup) where people put in 100 hour weeks and became zillionaires, there were 99 other places where everyone worked just as hard, and the place went broke. You have to have more going for you than wanting it. Luck helps.
You have to crush micros players to beat the rake. The biggest villain is the drop. Being the 3rd best player at the table might only make you a breakeven player. If you've studied and worked on your game, you could be much better that most players and still not a favorite to make much money.

Here are the serious tips:

1. Being a pro comes from winning so much at poker that it isn't worth your time doing anything else. It could be that you can't make much elsewhere and just playing poker is super fun, so the bar is pretty low. However, you have to currently beat the stakes you plan to play.
2. Ideally, you're playing high enough that you could move down and still pay your bills at a limit or two lower than you plan to play. If you need to win at NL200 to pay your bills, going pro at NL200 means you get a job your first downswing. Whatever limit you need to make your nut, your regular limit has to be higher.
3. In the long run, going to school can provide you with a lifetime of nearly variance free income. That's a big opportunity. Passing on that opportunity to "get good enough to play poker for a living, and then playing poker" can have a huge cost.
4. Whatever you do, don't half-ass school, get little or no value of education, and go broke/in debt trying to play poker on the side. The plan of playing poker on the side seems horrible, especially if you have to play a ton of hours to kind of pay bills + tuition. If you crush mid/high stakes and you can live large based on a few hours of play, ignore all the advice above.

A lot of people feel this way. Very few are correct. It's possible you're one of them, but just saying you have ambition and can beat micro stakes doesn't make me feel confident that you'll be a pro.

It's doable, so long as you don't have a social life. I would only recommend it for someone who has the willpower to prioritize poker over thinks like sex and alcohol and won't be psychologically harmed by doing that for several years.

I think OP would be better served by the experience of learning how to live frugally by virtue of being a broke college student rather than aspiring to live comfortably.

I'd probably advise against online poker, particularly given how green you are. Live poker is doable. However, like any business you gotta start small and build it...ie start by making money on the side with poker and eventually you'll be making enough money to pay your bills. Get student loans to cover your housing and tuition and make school your #1 priority. School should never take a backseat to poker regardless of how much money you make (or lose).
