Any idea about What is the difference between ‘Create website’ and ‘Create store’ ?

Creating a Store easier than Creating your own Website. There are a number of third party sites who offer you to easily build a store of your own choice. You don't need any technical knowledge most of them are free some of them may charge as well. Creating or designing your own website is a bit tedious process and requires technical skills.

Good Luck

stores are like shops in a mall where products and customers can be shared along with configuration setting s and administration. You would pick stores if you want one website with multiple faces. They share more than just administration but several setting configurations and checkout as well.

websites are like totally separate sites with distinct users, products and so forth sharing an administration and code base. You would use multiple websites if you would want completely different stores that you could manage in one place. They only share an administration log-in area.
