Was I wrong????

Ok, at least you seem to have the right attitude. But you're starting from zero. You need to start by understanding hand rankings. What equity one hand has against another before the flop, and the flop, on the turn and river. You best start by finding out what equity is, and how it is calculated.
Get PokerStove: Poker Software and Analysis and just play around with it for a while. I would advise against getting Holdem Manager or Poker Tracker just yet. It will just seem overwhelming and not make too much sense.

For example take J T and AT and run them through pokerstove. Then take some random flop like 93T and see how they rank up now. What about 93T? What about 345 ?
Every time you see a flop think: what's the best possible hand to have there... what's the second best? What hands could my opponents have, and how does my hand rank up against those hands, and so on.


Think about simple stuff like: Why are there blinds? What hands would I play if there weren't any blinds? What size should I bet and why? How does the size of the bet I face influence the hands that I can call with? Should I play differently when my stack is bigger/smaller in relation to the blinds, and why?
