How is my phone able to upload to cell towers that are miles away with its tiny 1W omnidirectional antenna?

Question

I get how the phone can download from the cell tower, because cell sites use 20-50W directional antennas, much more powerful than the phone, so they can cover a large area.

But the phone’s antenna is omnidirectional, usually 1W max. That’s as powerful as a Wi-Fi access point. So how can it reach the cell site 2 miles away? Is it because cell site antennas have high gain, so they can pick up a very faint signal?
