These aren't financial exchanges, they're a sports betting and an expense management system.

I share OPs skepticism. Market makers invest in microwave towers, FPGAs, etc. I would be surprised if sqlite backed by NVME is on the other end of all that specialized hardware.

Order matching is a single threaded thing though. I would be curious if anyone knows how electronic trading systems are actually implemented.

I was not making this assertion. I am surprised anything like it got inferred (i.e., my use of the word "premise" regarding single thread/writer policy).

I agree that what you describe would be ridiculous in practice.

I think you answered your own question.
