"This is why rooks are worth 5 and bishops are worth 3" Such evaluations are only a rule of thumb intended for beginners. It's all context dependent. There are positions where a Bishop is more powerful than a Rook. Other things being equal, Bishops tend to be preferred over Knights in serious play (especially when you've got a Bishop pair, which is synergically more powerful than one Bishop times two), even though both are theoretically "worth" 3 pawns. Two minor pieces are usually worth more than a Rook and a pawn, and more often than not it isn't a good idea to exchange the former for the latter, even though the total value appears the same (3+3 = 5+1). And so on.
