What is the difference between autosomes and gametes

An autosome is any of the chromosomes, except the sex chromosomes, while is the sex cell.  

Explanation:

Humans have 22 pairs of autosomes and one pair of sex chromosomes (pair number 23, made up of two X chromosomes in women and one X and one Y chromosome in men). Autosomes are numbered according to their relative size.

Gametes are the sex cells of multicellular and human organisms. They are haploid cells (that is, they contain 23 chromosomes, n), they originate by meiosis from germ cells (they contain 46 chromosomes, 2n).

During this process, germ cells mature and change shape until they become future gametes or cells with fertilizing capacity.
