The value is baked into the call_result variable you have there. The promise will be scheduled after query_staked_amount finishes and then once the promise finishes executing, the callback query_staked_amount_callback is invoked.

In this callback, the result of the original promise (get_staked_amount) will be available in that variable you have call_result.

Hope that answers your question.
