What is this phenomenon

Why is it that some people are good in subject which requires good memory like biology and ssc while some are good in maths.like some of my friends who are bad in academics are really good in maths ( kinda jealous), while I am really good in almost all the subjects expect maths ,why is there such a divide,is it genetics ( my father is a doc and hate maths) or is it related to brain functioning or something 😵‍💫😵‍💫😵‍💫
