No, it is not true.
Think about it for a moment. There are fewer than 92 naturally occurring non-radioactive elements. If "trace elements" made up 99 percent of something, then at least one of them is present in greater quantity than the remaining one percent. It's pretty silly to call the element which is present in the greatest quantity a trace element.
No, the four elements commonly found in living things (carbon, hydrogen, oxygen, nitrogen) are not unique to living things. These elements are abundant in the universe and can also be found in non-living matter like rocks and gases.

Carbon, Nitrogen, Hydrogen, and Oxygen are all found in abundance in all living matter.
A compound is a type of matter made up of two or more different elements chemically bonded together. Each compound has a unique chemical formula that specifies the types and proportions of elements present.
In any given sample of matter, you can typically find elements, compounds, and mixtures present in varying amounts. These can include atoms, molecules, ions, and particles such as electrons and protons. Each type of matter contributes to the overall composition and properties of the sample.
The 4 elements are Nitrogen, Oxygen, Carbon and Hydrogen.

65.0%.
The four elements comprising over 90% of living matter are C, H, N, and O.
Carbon, hydrogen, oxygen, and nitrogen are the four essential elements that make up most living matter. These elements are crucial for building biological molecules such as carbohydrates, lipids, proteins, and nucleic acids, which are essential for life processes.
The valence of hydrogen which is a common element of living matter is 1. The other elements are oxygen which has a valence of 2, nitrogen has a valence of 3 and carbon has a valence of 4.
The elements that make up the largest portion of living matter are oxygen, carbon, hydrogen, and nitrogen. These elements are essential for forming the building blocks of life, such as proteins, nucleic acids, carbohydrates, and lipids.
Elements found in small amounts in living things are called trace elements. Among the trace elements that have vital functions in humans and plants are boron, chromium, selenium, and molybdenum. Of course, the natural element present in the smallest amount (not at all), which is not necessary, is francium.
Oxygen (O)Carbon (C)Hydrogen (H)Nitrogen (N)These four elements make up 96% of living matter.
Carbon, hydrogen, and oxygen are the three primary elements that compose all living matter. These elements are essential components of biological molecules like carbohydrates, proteins, lipids, and nucleic acids, which are crucial for the structure and function of living organisms.
Humans only source their food from living matter. We eat only vegetable or animal matter. At present, no planets other than Earth are known to contain living matter.
