You're right that it is impossible to transmit information via quantum entanglement. If we share two qubits of an entangled qubit state, nothing I do to my qubit can change the outcome distribution of any experiment you do to yours, or else I could use this link to transmit information to you faster than light, a big no-no.
What quantum teleportation allows one to do is to transfer a quantum state in my possession (call it target state) into your possession, despite only sending two classical bits of information over a classical channel, say a number 1 through 4. This is surprising, since the target state may have been unknown to me, and were it known, it could take an unbounded amount of information to specify. But, the transfer is bounded by the speed of light, since you have to receive the two bits I send you to do your part of the protocol.
The protocol requires us to share one qubit of an entangled state in advance, which will be used and consumed by the protocol. Afterwards, I am given some third qubit in the target state which I want to send to you. The protocol ends with your half of the shared state being the target state, and me not having the target state any more, which is necessary, since the target state cannot be copied by the No-Cloning Theorem.
He keeps differentiating, flying off on a tangent.
