Sounds correct because you must also judge your opponents cards as well, otherwise even a good hand can lose to a better hand and worse is if you have wrongly place too much confidence and too many chips with your strong hand.
Sometimes a player is just going to be unlucky while even having good cards, if the other players also have a better hand.   So to make up for those losses, playing an average hand like its worth something and beating or realising the other players have a weaker set of cards is going to be necessary.  Its all relative!
