Ok, pot odds...
pot odds are the ratio between total pot and the amount you need to invest to win the entire pot. Lets say there is 10 bucks in pot and someone bets 5 bucks, you need to pay 5 bucks to win 15 bucks which is 3 to 1 or 3:1, that means that you are winning 3 times more money than you invest in pot. Now if the bet was pot size you would have 2 to 1 pot odds to call. You understand the math right? Total pot, bet included opposed to your investment needed are pot odds.
Now like in my previous post pot odds itself also doesn't mean much. but if you use them with hand odds you will have clear image of what you should do in every pot lets say that you have oehe on flop the pot is 10 bucks and for the sake of simplifying the example ill say that opponent have only 5 bucks left and he ships it in, like i said it above that is 3 to 1 pot odds to call, now you should look at hand odds and outs and see that you have 32% chances to hit the str8 which is little worse than 2:1. What that means, that means that you should always call when your hand odds are better than pot odds, or bigger percentage of you hitting the hand than percentage of money you need to invest in the pot, that way win or lose you will be winning longterm in that kind of hands because when you hit with that hand you will win more money than you lose each time you miss the draw, this is also called playing within the odds, opposed to this playing against the odds would be lets say that you are on the turn with oesd and need to pay pot size bet, pot odds are again 3 to 1 but this time you have 16% chances which, is worse than a 4 to 1 hand odds and you should fold, because you would lose long term if you call...
I intentionally used the all in example because it is easier to understand the concept that way, with possible more money to come in later streets it gets slightly complicated with implied odds and reversed implied odds but you will get there, make sure you figure this out so far...
I hope that this is helpful, feel free to hit me if you need anything...
