The other states haven't finished counting either, they have a large margin for one candidate, so the remaining uncounted votes are extremely unlikely to changing the leading candidate.

In swing states however, the probability of uncounted votes changing the leading candidate is much higher, which is why the news is focusing on them.

This is just the impression you get because the swing states are the ones that are close.

All of the states are still counting votes, it just won’t matter in Oklahoma or California. For the president that is. Down ballot elections are still contested everywhere. Illinois which was predicted for Biden moments after the polls closed has a Congressional election that is coming down to provisional votes and this hasn’t been called yet.
