Hi @paulyeo11
Welcome to Power Automate 🙂
When you say "Power Automate" it could mean multiple things.
Therefore firstly let me introduce you to the naming conventions.
In Power Automate there are two types of flows:
i. Cloud flows
ii. Desktop flows (RPA)
Cloud Flows are developed via https://flow.microsoft.com/
Desktop flows are developed via the Power Automate Desktop (PAD) tool which you have installed you said in your post.
Desktop Flows can be called from Cloud Flows too.
Both of these fall under the Power Automate bucket.
So when you refer about wanting to learn "Power Automate" it could mean both and it is highly recommended to learn both.
Lots of YouTube Videos are available for both.
I found below paid training helpful. It has more of Cloud flows, but also has topics on Desktop flows.

Prices keep changing so keep a watch to see when it is low.
Good luck!
