Because, in the very distant past, humans and worms had a common ancestor.
Humans have around 20,000-25,000 genes in their genome, similar to that of a mouse. Fish species may have varying numbers of genes in their genome, but generally have a comparable number to humans and mice. There is significant overlap in the number of genes found in human, fish, and mouse genomes.
The estimated number of genes in a human cell is around 20,000 to 25,000. However, this number can vary depending on the organism and its complexity.
The human genome contains approximately 20,000-25,000 protein-coding genes. However, the total number of genes in DNA varies among different species.
Humans have 23 pairs of chromosomes. 22 pairs are homologous (basically same shape) and the last pair is known as the X and Y sex-determining chromosomes. You were correct that 23 come from mom and the other 23 from dad. With regard to the question about genes, scientists finished sequencing the human genome in 2003. They found that the genome contained only 20,000-25,000 genes. You can read more about it if you search for human genome project on the net.
The exact number of base pairs in all mammalian genes is not known due to variations between species. However, the human genome contains approximately 3.2 billion base pairs. Mammalian genomes are generally similar in size to the human genome, so the total base pairs in all mammalian genes would be around this range.

there are 42 chromosomes in the human body
There are more genes than chromosomes in skin cells.
It was expected that we will find out about 1,00,00 different genes before Human genome mapping was done. In fact, we could find lesser number. Different books give different number but number is probably between 20,000 to 25,000. We got psychological depression, when we found same number of genes in round worm also.

I'm pretty sure than human and chimpanzees differ by 1%, that our DNA is 99% similar. Not sure but that's what I've heard

The human genome contains about 24,000 genes.

it is because they have genes
