Top grandmaster? No. A grandmaster? If you have a lot of tallent, get a coach, work really hard, have money for tons of tournaments, are low rated only because you are new, then probably no. But it would not be impossible.
Can a person below 1000 become a top grandmaster?

yeah You Can.. But it depends on your dedication and determination towards the game!
I have that.

I went over a few of your games and I think you are strong for your rating. If this is just a hobby then get a diamond here and use chess mentor along with tactics trainer and the videos. If you want to get serious then get a coach. Get over the top GM goal for now. Study properly and hard for a year or two to see what it is really like and how much ability you have. Then set incremental goals. You really should not be making decisions about going for GM till you are IM. So many prodigies do very well and do not make GM. There is nothing wrong with that. GM is something special like an olympic athlete vs your high school or college track star. They all work hard, but the best work insanely hard and have a gift for it.
I was wondering if even though I have a low rating below 1000, could i still become a top grandmaster. I'm in my early teens right now.
Every top grandmaster began as a 700 rated beginner. The key quality needed to excel at chess is social awkwardness leading to a lack of any social life and thus a strong focus on chess as a substitute for a social life.

Not sure of your age, but if your not a Master by your teens, it wont happen at all. Nearly all chess Grandmasters were prodigys at an early age. Hard work will only take you so far if you dont have the natural talent to go with it. Otherwise we would not all be Grandmasters?

I really think it's a matter of how much natural talent and intelligence someone has. Let's be honest - The guy with the 85 IQ could spend 100 years playing chess and he'd still be a terribad. His potential is gimped beyond belief. On the other hand, if someone is brilliant, displays a natural talent for endgames, and spends most of their time over the course of 10+ years studying and playing - I don't see how they couldn't at least hit 2200.
Someone please correct me if I'm wrong...

I think your IQ improves as you play chess.

EDIT: If I was to get my official FIDE rating, I don't think I'd be this low. Probably around 1100. I am better in real life than on here.
If you start working very hard you can become a very strong player.

Na, I think they are over 1000 out of the womb. Not checked, but I don't think I've ever been below 1000 and I have no chess talent.
The answer is almost surely not. People who become really great at things start out pretty great at those things. And everyone has a maximum limit that God gave them that no amount of training or dedication or luck is going to push them past. In particular the comment above that "every GM started as a 700 player" is just not true. Most people who become GM's picked up the game so quickly that by their first tournament, they were 1400 players or better. Titled players work hard but every last one of them is gifted. If you don't have the gift (and virtually everyone doesn't), there isn't much you can do about it.
After you try hard at something for 5-10 years, you can pretty easily learn how good you could be at it. For virtually everyone in chess, it is some rating number less than 2100 or so. The people who become great GM's are beating everyone in sight by age 14 or 15.
I've even seen people with gifts flame out. At my old chess club we had the guy who broke Bobby Fischer's age record to USCF master named John Jarecki. I don't know what John is doing now (I hope he is happy and productive and healthy and even playing chess) but I think John never made it maybe to 2300 and never earned a title (pretty sure and if I am wrong, I regret it).

I think the answer to the question is "yes" as even top grandmasters had to learn the moves and right after they learned the moves--their skill level was probably under 1000.

EDIT: If I was to get my official FIDE rating, I don't think I'd be this low. Probably around 1100. I am better in real life than on here. I am right now getting used to playing on a 2D board. Right now, my problem is making hanging blunders that I don't make in real life.
