While loop & if statement

After I watched this video, I have been seeing that the if statement is basically a while loop. Is this true? What is the difference between them?

No a if statement and a while loop are two different things, A if statement is there to check if a condition just happened and if it did it will run either wise it will do something else. So a example of this would be if a button is pressed it would check if the button was pressed once then it would execute something.
A while loop will continually check for something until that value becomes false. So for instance if i have a button press and i want the words hello to display on the screen as long as that button is being pressed the while loop will keep checking and printing hello until its released. Hope fully this clears things up a bit.
