Are modules == mixins in ruby?

I read in many textbooks that

In Ruby, a class can only be a subclass of one class. However, mixins allow classes to share methods without a common ancestor.

In practice, when I need to implement multiple inheritance. I use Modules, not mixins. eg:

Module name_goes_here
  def method_name_goes_here
    .....
  end
end

Then I just include them in the class

class MySubClass < MySuperClass
  include module_name
end

Now I have mentioned several ruby ​​books, each one talking about mixins, and then all of a sudden they all start talking about modules, making it clear what the ratio of mixins and modules is.

so, Question: Are the modules == mixins in ruby? if so, why. if not, then what's the difference?

PS: sorry if its a stupid question
