This is dependent on the TRIM schedule. It could be size based (execute a TRIM when 50% of the blocks are used).
It could be or maybe the SSD has its own on-firmware TRIM schedule, but all major OS's execute a TRIM on a time based schedule no longer than every 10-15 minutes.
Afaik the default for windows 10 is weekly via disk defragmenter, and that assumes it recognizes the drive as an ssd. I've had drives cloned to ssds that retain the hdd flag and had to setup a 3rd party tool that actually saw it properly and would trim as expected.
11 might have reigned that in... but probably not.
Perhaps, but this is unrelated. The magnetic charges may still be there, but if the reference to the content is deleted, how is the filesystem meant to know what file is there? This seems really suspicious to me.
TRIM works outside the filesystem, it does not care about 99.9% of it, the only part it cares about is if there is a reference in filesystem to the block charges. No reference == data to be released
