Absolute beginner from the UK

Hello everyone,,

I want to know what are the very basic drills i should be doing, I'm 22 and i feel it's a bit too late to go to team tryouts without atleast knowing the basics.

I live near an outdoor court and go there to practice sometimes but kinda feel like i have no idea what I should be doing.

Here's a good workout to start with:
