Both

 

“I’ve got you.”

“They’ve got you.”

Does this mean:

Either,

“I/We comprehend what you are talking about?”

Or,

“Caught you red handed.”

? 

There is a third option:

It means Both.

But you can not use it to mean both meanings at the same time. 

So,

Which universe are you in? 

How do you interpret?

Do you even bother to check your interpretation is the same as the intended meaning?
