As far as I can tell, you can split Gen Z (as it is commonly called) down a line when it comes to technology.
You have PhoneZ; They had a Phone from a young age, and never had to use a computer for just about anything; I've heard them describe computer use as performative and not actually useful.
And you have ComputerZ; They had a Computer from a young age. They probably also had a phone, but they USED their computer, so they're actually somewhat competent. They know how to use a mouse, how to type, etc.
There are two reasons why ComputerMillenials are more so much more common.
We didn't have smart phones, which is a given, given our age group
We actually had computer classes; so we learned how to use computers from a young age.
Because of point 2, the older generations decided "The kids already know how to use computers" and stopped teaching those skills, causing PhoneZ to become a much larger group of people, which is a decidedly not good thing.
