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.
