It will be the largest number though. They’re the only ones that are bothering to do such a low orbit, because that gives you lower latency but means you have to have a lot more in orbit for the same coverage and they don’t last as long before the orbit decays. They can do that because the launches are basically free

The current amount is only about a third of the total planned amount.

Oneweb is medium altitude unlike starlink which is low altitude, so you don’t need as many. It doesn’t have as much capability but it’s fine. But when starship is operational there will be plenty of capacity to launch a lot more sats and get more capacity.
