This is fundamentally not true.

Light is made of electromagnetic waves. If you can control the timing of those waves precisely enough, you can add another light with the opposite phase (an inverted wave) that will cancel out the other light.

This is what happens in the famous “double slit experiment”. It’s also the same principal as noise cancelling headphones albeit with sound pressure waves instead of EM waves.

Scientists have actually cooled atoms very close to absolute zero by shining a laser at them
