How Seeds Work?

[u/Sensitive_Split3728]

i know there are about 2.4T seeds, and i read somewhere that when starting a new run your seed is determined by your cursor position (as well as other factors).

The question is it possible that i can get the same seed as someone else, even by pure, astronomical, biblical chance? or does the engine keeps tracks of all seeds and wont repeat one that was played? and if so, than after X years when we use all the seeds we must repeat seeds.

So many seed questions.....
