Google and previous gave me conflicting answers. Some said DNA are the biggest. Some said DNA are the letters, genes are the sentences and chromosomes are pages. Please help.

Chromosomes are structures used to store DNA.
DNA is the specific tool used to store instructions for building and running a body.
Genes are batches of instructions for specific things which are encoded in DNA.
So: The chromosomes make up an instruction manual for building you. The genes are individual sections of the instruction manual of varying length and purpose. DNA is the actual letters and words that make up the sections.
Very ELI5 but hopefully that gets the idea across.
DNA is deoxyribonucleic acid. That’s the chemical that is the basis of it. Think of this is the paper and ink that everything is written in. This chemical can form into long chains. So that “paper and ink” can be as long as you need it.
Chromosomes are the “books”. There are 46 chromosomes in a human cell. These chromosomes are individual long chains of molecules made up of the DNA.
Each of those chromosomes will have small sections that work together to form proteins. Those sections are the genes.
nukleotide<gene<chromosome<genome
Genome can be sometimes called “DNA” as in “it is in your genome/DNA”
Genome is all of genes. But DNA is more of a material.

Genome is all of genes. But DNA is more of a material.
DNA is a chemical (deoxyribonucleic acid). DNA is like a chain, and the molecule can have anywhere from 1 link to billions in that chain.
Chromosomes are structures made of long strands DNA, sometimes wound around bits of protein.
A “gene” is a unit of inheritance. The concept of genes is older than our knowledge of DNA and chromosomes. As we began to understand the role of DNA, a gene was originally understood to be a location or piece of a chromosome. Today, we tend to think of it in terms as a specific DNA sequence that’s typically part of the longer DNA molecule that makes up a chromosome.
Chromosomes are DNA, so you can’t really say one is bigger than the other. Chromosomes typically have multiple genes along their length, so we say that they contain genes.
Genes can get pretty long (the Huntington gene in humans is 180 kb long), and chromosomes can be pretty short (the human mitochondria contain 17 kb circular chromosomes), so you can’t say that chromosomes are always longer than genes. Chromosomes are longer than the genes that they contain.

this is like asking, “which is bigger, a page, a book, or paper”. The question makes no sense, because the both the book, and the pages of the book, are made of paper.
the genes are made of DNA. Chromosomes are just a whole bunch of genes on the same strand of DNA.
