This means that her paper wallet will not have any balance left and she will not have the option to access those 7 BTC, as they were moved to a change address that isn't in her possession.
Alice could physically set the outputs of her transaction to incorporate both Bob's address and one more address that she controls (to send the change back to her) - however this would require some technical information. Assuming Alice neglects to make a change output for herself, the excess 7 BTC could be taken by the miner that approves that transaction's block. Subsequently, she would be better off sending the whole balance (10 BTC) to a cryptocurrency wallet software, like Trust Wallet, and really at that time send 3 BTC to Bob.
