They take it all seriously. That’s why they require a financially appropriate sponsor and allow for a joint sponsor . 

Friendly reminder to keep the language on here clean.

Quite correct. I had forgot we were talking about the K1.

I134 for the visa.   I864 comes later 

If it's just the intending immigrant and the sponsor (household size of 2) the minimum is $21,137. So you should be fine.
 
Note that your sponsor still much complete a i864, even though she does not qualify to sponsor you.
