What does "crm.objects.users" refer to?

I am working to learn about and create a Private App. I have no knowledge or experience with APIs or Private apps. I have a general understanding that this is a process to send and get information between platforms.
I am working through setting up my Private App and am selecting Scopes.

I have encountered two different scope types for users: “crm.objects.users” and “settings.users.”

I am struggling to fully understand what each of these mean and how allowing them access would impact my Private App. I have looked at the Summary of Selected Scopes shown here:

I am still not confident I get it completely. I understand that settings.users refers to allowing things like creating users and updating their permissions. I am not as clear on what “User CRM object data” refers to.

Could someone please help to clarify this for me, in the simplest, most “this person doesn’t have a clue” way possible?
Thanks in advance!
