Overkill.
No. It's overkill if you don't refine your questions. If you ask too vaguely, you'll get much more info than you may need.
Do you know how banks send the money internally, how they store them, how your VISA card communicates with the bank when inserted into a PoS? I guess not. Then why you try to focus on all the details for Bitcoin?
You need to understand a small number of things:
1. Wallet safety and computer safety.
2. How to look onto a website to check if the fee you choose is right.
3. Install and run a simple wallet, like Electrum, how to send and receive.
4. [Maybe] How to check on a 3rd party website if a transaction was sent and confirmed.
This means that you need some 15 minutes to pay attention.
Talking about algorithms scares people.. for sure people don't know how their cards, tvs or phones work. They also don't need to know about mining but is good to know how wallets work. I think all explanations should start with the concept of decentralization and why they should own their keys and keep them safe.
