Genes code for a particular amino acid which makes a particular protein.....
A sequence of 3 base pairs code for a specific amino acid.....
Does that mean that each gene is made of 3 base pairs?

So, a gene is a section a DNA that codes for a specific protein.
Proteins are made of amino acids bonded together
Amino acids are sequenced by something called a “codon”. This “codon” is a three base sequence (e.g. GGT) that codes for the amino acid Glycine. So it’s a little bit like a three letter identity badge for an amino acid.

Hope this helps!

Genes dont really code for a single amino acid

Rather, genes are stretches of DNA that code for stretches of amino acids (proteins) via transcription, processing, translation and then post-translational modifications such as glycosylation to yield the final functional protein

So 3 base pairs code an amino acid and a gene codes for how many base pairs there are, which ones and in which order??

3 base pairs, any sequences of bases. This link my show it a bit better:
