3 Ways to Identify Your Customer Segment

Customers segments have something in common with each other allowing you to reach them more easily by knowing what their interests are, where you can reach them and what do they need.
Here are 3 ways that you can define your customer segments if you are a startup:
1- Mass market includes a broad range of people that could be interested in your offerings.
2- Niche Market includes a more specific group of people that come together because of their age, location, and interests.
3- Multi-Sided Market which is specific to companies that have users of the products or service who could be using it for free and clients who have an interest in reaching that set of users.

Good job

The part I require help with is Customer Segments which is the first building block of a business model according to the book. The part that is confusing to me is that it mentions "There are different types of Customer Segments. Here are some examples:" it goes on to list 5 different examples which are 1. Mass market 2. Niche Market 3. Segmented 4. Diversified 5. Multi-sided platforms.
Questions I have:
Are these 5 different examples different ways you can classify different customer segments?
Is the "Mass market" example actually a customer segment? Because it says "business models focused on mass markets don't distinguish between different Customer Segments" does that sentence actually not make it a customer segment since it does not focus on customer Segments?
Could you consider age, behaviour, or geography different types of Customer Segments?
