Back in the 17th century lots of Calvinists concluded/feared themselves to be not part of the elect.
The criteria of defining this is rather…different.
On the one hand, you got the OG Dutch Calvinists that were easy to convert because their criteria was "wealth and riches are an outwards expression of being elect" and since a lot of those Dutch were middle-class spice merchants lots of them were saved.
On the other hand, you got a Prussian king who feared he was not part of the elect despite his wealth, successes and riches.
What criteria the latter used I do not know.
Tl;dr: yes, there are Calvinists who consider themselves not part of the elect.
