Transaction Wallet-Address extraction?

I am currently trying to extract data directly from the blk.dat files from bitcoin core but when taking a look at the blk.dat files I am confused about how I would go about getting sender(s) and receiver(s). It is clear to me that if I have multiple inputs / outputs that there might be multiple senders / receivers but how do I determine them?
If the transactions in the blk files don't allow for that then how do I figure out who sent who what?
I do not need a 1 to 1 mapping of transactions, if 5 people combined sent 7 other 3 BTC that is perfectly usable data for my purposes as well.
My main resource was https://learnmeabitcoin.com/technical. But I tried finding information elsewhere with no success.
Thanks in advance!
