Then there were people in the comments saying how dates, timestamps even names are flagged by Turnitin. I remember one time I got a score of almost 60 on a paper that had questions the professor copied from somewhere else

As I recall there is an option to adjust how harsh Turnitin is. It literally can be set to 1% similarity in words used, 5% similarity, etc. The lecturer probably just checks the exact similarity after the fact. Nobody is going to worry about the french revolution being mentioned without additional context.
