Hello brother
Position does not mean power, but it does mean that you can have a bigger vision of the game or the table depending on where you are.
For example, the most difficult position is UTG, because at a table of 9 players you start the hand, if you open you have to do it with a good hand because you have 8 players behind you who will act accordingly.
Those who know say that in UTG you have to open minimally with 99 to major and then see how the table acts.
BB is the best position, 1st because everyone at the table plays before you, you can make a correct decision even a bluff or semi-bluff. 2nd because you have the obligatory bet, if you have many limp players at the table, with lousy cards in your hand you can do a quiet check and see the flop, maybe luck is on your side.
To have power is what my friend Andyreas says, it is to have good hands and have a preflop or showdown to make the best hand and maximize it, even getting the nuts of the hand.
In general, the problem you have in the cash tables is that no matter how much position you have, if your opponent was told that you have AA and he has 35 and he is going to beat you, he will pay you in whatever position you are.
Many times the cash tables are very cruel, that's why I generally don't like to play them. I prefer MTTs or SGNs
