Theres no difference between price and value over a long period of time.
AA and KK are the only two hole cards worth more than the blinds.
Your hole cards mean very little in NL - it's your opponents, position,rep and post flop play that determine your win rate.
for one player KJ can be a loser over a hundred thousand hands.. for another player it can be (statistically rigorous) a winner....
In limit there are well known starting charts but even these get modified to table..
If you want to learn poker - put a sticket note over your cards on the screen and play blind... you will progress much faster
