You could simply remove MonoBehaviour from your variables class declaration. Then, to use it, write public Variables vars;, and you should be ready to go.

EDIT:

But, always remember: if it doesn’t work, write: public Variables vars = new Variables();

Man... That's getting hard, since I don't have my computer to test it right now, but... Let's see what I can do for you.

Try to do this on a test scene just for testing sake. If it works, then your script should work, if you did everything alright.

 public class MyExample : MonoBehaviour
 {
     public Variable vars;
 
     void Update()
     {
         vars.money++;
         Debug.Log("Money" + vars.money);
     }
 }

Try setting the variables class to static, then you should be able to reference it without an object reference.

You declare the class like this:

 public static class staticClass : object 
 {
     public static int count = 0;
 
     public static int()
     {}
 }

And the you just reference the class by its name:

 int i = staticClass.count;
