Pretty close. Your post was mainly describing POT odds. Which are a straight up calculation of how large the bet you have to call is compared to what is in there to win.
EXAMPLE HAND
The blinds are 10/20
You are the BB
Folds to the Button
Button raises it to 50
SB calls
Right now the pot is 120 (20 from you, 50 from button, 50 from SB) and it will cost you 30 to call. Right now your pot odds are 120:30 or 4:1. Your hand is A 9 so you like your possibilities and are getting very nice pot odds, so you call.
Flop comes 2 Q J (Pot=150)
Action after the flop is to you first and you decide to check.
-----------------------------
Scenario 1
Button bets 50
SB calls
Right now the pot is 250 and it will cost you 50 to play, so 250:50 or 5:1 are your POT ODDS (very nice by the way). Next lets look at your outs. Another heart would give you a flush. There are 13 hearts in the deck, we know where 4 of them are, so 13-4=9 outs for the flush.
An Ace might be an out, but it might also give someone else a straight. Or on this case it could easily give one of your opponents 2 pair (they both paid to play with some kind of cards AQ or AJ are quite possible here). There are 3 A's we haven't seen but because of the tainted posibilities lets just call it 1 out here.
There is the possibility of some miricle draw like 99 or A9 or AA giving us something good, but those are slim enough not to bother counting IMHO.
So where are we?
9+1=10 outs
That means that of the 47 cards left there are 10 that will help us and basicly all the others wont. So 47-10=37 bad cards and 10 good cards. We figure the odds of winning are 37:10 or 3.7:1 against us.
We can compare 5:1 pot odds to 3.7:1 odds and we have an easy call because the ratio of what we stand to win is greater than the ratio of the chances against us. Over time, making this same move in this same situation WILL MAKE MONEY FOR US.
-----------------------------
Scenario 2
Button goes all-in for 150
SB folds
Right now the pot is 300 and it will cost you 150 to play, so 300:150 or 2:1 pot odds.
Your hand and the flop has not changed from the last scenario so our outs have not changed. We compare 2:1 pot odds to 3.7:1 and we probably want to fold here. Why? Because the ratio of what we stand to win is less than the ratio of the chances against us. Over time, making this call in this same situation WILL LOSE MONEY FOR US.
-----------------------------
Scenario 3
You have 2000 remaining
Button (fish) bets 150 and has 2000 remaining
SB folds
This is basically the same betting scenerio as the last one, but this time notice that there is a good chance that much more money could be made if you do hit one of your outs. How much? Well lets say that you feel this player will call anything you bet no matter what card comes (yes there realy are some people out there who will do that.. isn't it great?). This means that your IMPLIED ODDS are 2000:150 or 200:15 or 13.3:1
Implied odds are much less reliable, because you can almost never be sure of their value. A player who usually calls in a given situation wont ALWAYS do it. But keeping in mind there there could be a lot more money to be made if you play it right is definately worth considering.
