Teleportation in that term means “make a thing disappear in one place and appear in another”. No “immediate” is ever implied.
Wikipedia article has a great diagram on the topic. Add an article on “no cloning theorem” to understand why “teleportation” is a fitting term. I recommend reading both without expectation, just read through the steps as if you’re learning a new math tool.
In short, quantum teleportation is a way to take a quantum state (which are fundamentally unforgeable - you can’t simply create a clone of a particle), destroy it, extracting classically communicable data, and they recreate it in another location.
