No, living things don't need to be directly in light to live.
The whole food chain always goes back to light, though - worms eat the rotting remains of plants which needed sunlight to grow, so in a way all life depends on daylight (except certain bizarre life-forms that get their energy from geothermal sources on the ocean bed, but that's really a whole other topic).

No it is not that all living animals need light to survive... it is that almost all creatures are ultimately dependent on the energy from the sun to survive... basically its because of the food chain, plants convert sunlight into energy to grow(photosynthesis), other animals feed on plants, animals feed on plant eaters etc. Even animals in caves and deep under the sea ultimately get thier energy from the sun because they feed on creatures that eat plants or creatures that eat plant eating creatures. Recently though the discovery of extremophile bacteria that live without ever drawing energy from the sun, like some that live deep in caves called "Snottites" which feed on sulfur compounds and produce sulfuric acid. This proves that not all life is dependent on energy from the sun, but most is.

Obviously you've never heard of stygobites (not sure if I'm spelling it right), and I'm not surprised, very little is known about them. Whole worlds of these creatures exist where there is no light, in tiny holes that lead to small caverns in what appears to be solid rock. There were some found in Australia within the last few years.
And DriverRob has obviously never heard of diatoms or algae.

Worms do exist off the biological material that was made possible through photosynthesis so it can be said they live off the "light" even though they do not require direct light to survive. That being said, there are bacteria that live deep within the earth and at vents that arguably do not live off the light. They live off chemicals.

Not all living things need light to survive. In some cases, light is bad for them becausse they are so delicate. There are entire ecosystems in caverns where many of the inhabitants never see the light of day. These creatures have evolved minus eyes and skin pigmentation because they simply do not need it in their lightless environment.

There are many things living at the bottom of the ocean that never see any daylight. Many wonderful and beautiful and very ugly things i believe that would look like they came from a horror movie!

Only green plants need light to live.

Not all living things need light itself to live. They need light energy to live. Plants need light energy to live, and animals eat plants. So animals get light energy from plants.

No worms moles voles and many more things thrive better in the dark.

The statement that all living things need light to live is false.
