The short answer is it's not very easy. The long answer is if you have some time and you have a little bit of patience, Google Amazon Seller University that will give you every bit of information you need to continue on your journey. If you would like some advice I have had an Amazon store for about a year and although I don't consider myself an expert I do have some knowledge. You could message me and we could maybe do a zoom call and you could ask some of your questions. However, try out the university and see what you can see! Hope this helps.
