Is 767 Elo bad for 10 minute rounds

I am around the 700-800 range. The only time I played chess was when I was in elementary school which was a long time ago which I was in the chess club at that time. Basically I knew the rules of chess, the value of pieces, and some general strategies.

I haven't touched chess in nearly a decade, I am 22 now. From when I started getting back into chess a month ago I was in the 500 Elo, I was basically making blunders where I would of caught it right after I made the move, or just very bad openings that would cause the game to collapse. 

I am slowing climbing, and wondering what this Elo would be considered. What would be the average Elo? For example if you had everyone in the world who knew the rules of chess, play several games what would the average Elo be?  

I studied more about openings and how to develop the pieces at the beginning of the game, my most common openings are Ruy Lopez, Sicilian defense, Queens Pawn, and Indian. I know the opening isn't everything but since at these low elo's a lot of players play some crazy stuff at the start, so the opening has helped give me an advantage where sometimes I would able to gain some material or just have more pieces involved/ better positioning.

It's not good, but whether it's bad is subjective.

You will learn a lot by playing chess.   If I were you, I would start with a 20-minute game, so you have time to think.  But for practicing a particular opening or a certain technique, use a 10-minute game.

ALso, don't care about your rating too much in the beginning.  It will go up and the more you read about chess in a good book or use the computerized chess lessons here on chess.com, the better you will get.

I've been practicing an opening for about year now, trying all the variations in both black and white.  Over time, I've come to see some very subtle things that can make the difference between winning and losing.

I*m not saying you should spend a year practicing just one thing.  But maybe it helps to give you some perspective on how much time you COULD spend if you wanted to.  Me?  I'm just too lazy to dig out my chess book and look up another opening   One of these days...

Also, when you play a lot of 10-minutes games, you will learn to recognize types of opponents - the relentless queen-taker, the pawn advancer, the totally clueless, the guy who puts up a big defense and doesn't budge hoping your time will run out (particularly annoying when he (or she) is white), and so on.

Mosly, have fun because chess is not only good enterntainment, it's good for your brain and self-discipline.  As with any online gaming platform, you will learn to exercise good manners and reign in your negative emotions when you encounter players who don't walk the high road.    But in chess.com this is a bit easier because it prevents you from typing some profanity (which can make you even feel more annoyed )  That's one thing I like about chess: above all else, it's a game of good manners. 

Chess will tell you if your mind is sharp or rather dull at the moment.  It will also let you know what kind of mood you're in.  For example, I can tell I'm in a particularly good frame of mind if I type in chat "en garde" when the opponent has thoughtlessly put his/her queen in danger.  And ... once in a while, I take great delight invoking en passant, imagining the other player scratching his/her head as they try to figure out what just happened.

Of course, once you reach the higher ranks, you will need more tricks up your sleeve to catch the experts off-guard.  Er... ahm... en garde... um... nevermind!
