Apache Spark is written in Scala programming language. To support Python with Spark, Apache Spark community released a tool, PySpark. Using PySpark, you can work with RDDs in Python programming language also. It is because of a library called Py4j that they are able to achieve this.

@11:39 - it does not look like it s due to the index, I think internally it sorts the strings and then show min as lower and max as highest point in the sorted array

What I noticed is 'Describe()' function gives the data types of Age and Experience as Strings, not Integer. But 'Describe' method gives the correct data types as Integer. In addition, df_pyspark.describe.show() does not work, but df_pyspark.describe().show() works successfully.
