println() only prints a line of text. printf() provides string formatting. You can't use format specifier like "$s" to print a variable value as string using println().

here is because it gives us a lot more control over what our output will display like. So do not look at this as a case of Java not having a specific method you have used before, instead look at this as another tool to add to your java tool belt, in this case using printf
to better format your output.

So the function that he is using in the video is System.console which he has assigned to a variable console. The documentation for the System.console class can be found below.
https://docs.oracle.com/javase/7/docs/api/java/io/Console.html
You are probably familiar with the System.out.println function that is the standard output and not specifically the console output. Documentation below.

Hope that helps
