You’re not wrong. It appears to be a very garbled technical explanation. Mainly that organisms need to absorb low frequency/energy light while reflecting higher frequency/energy light. I’m guessing that chemically that’s harder to do.
Molecules that appear blue must absorb very small amounts of energy, while reflecting high-energy blue light. Since assembling the molecules that are capable of absorbing this energy is a complex process, the color blue is less common than other colors in the natural world.
