Can really transactions with fee

I ran into this fee calculator: https://bitcoinfees.net/

If I'm interpreting the page correctly, there are transactions under 50 sat/vB that did settle (or expected to settle) within a day.

I'm not sure I understand how this is possible at the moment, since there's a huge bulk of transactions with much higher fees. So, the lower fee ones will have to wait for many days or weeks until all or most of the high fee ones are settled.

Exactly like, one is waiting for the train, but there constantly other passengers with higher priority tickets arriving and being boarded before.

Is this page simply calculating incorrectly?
