AVL Tree rotations : How to balance below AVL Tree with imbalance at root node
Oh, my goodness. That AVL tree tutorial at tutorialspoint is so misleading that it is the reason why you became confused. Please ignore that tutorial.

Please study the AVL tree insertion article at GeeksForGeeks instead. Or check some textbook such as Introduction to Algorithms by By Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest and Clifford Stein. This recommendation should be one of the best help you can get from asking a question.

In the graph you last uploaded, https://i.stack.imgur.com/0HivT.png, the change from the first tree directly to the last tree is called a right rotation by almost every textbook, tutorial and articles I have seen. The tree in the middle never appears. The tree in the middle is just an extra unnecessary distracting step.
