That isn't how elections work. You can't assume that all voters in non-swing states would never change their vote.
You could say the same thing about a popular vote where a candidate wins by 10 votes - "oh, our entire system is decided by 10 voters? how unfair"
For the US election, votes in other states resulted in a situation where only 5 were swing states. If those voters in non-swing states voted differently in enough numbers, then there wouldn't be just 5 swing states.
Look at any of the elections in the past 40-50 years and you can clearly see that which states are "swing states" and which aren't changes over time.
