Hi@akhtar
As mentioned, there are no such prerequisite skills required to start with AWS. It depends totally on one's determination and hard work to grab the knowledge and concepts. For a beginner, I suggest to take an AWS course as it will guide you with right knowledge and help to understand all basic to advance level concepts of AWS with some use cases.
Here, I have attached the link of AWS resource.You can go through it.
