How does Bitcoin work?
Basically Bitcoin is a digital journal that keeps track of who has Bitcoin. Banks in general also have journals like this to record customer A has how much money. What distinguishes Bitcoin is that digital journals are not stored in a particular agency or party.
In Bitcoin, these digital journals are stored on each person, or anyone who wants to own and assist the transaction process (called maintainers). So when a digital journal breaks down then you have a backup of all other users. No one party controls this journal, everyone participates.
But since everyone can have this digital journal then they can know the amount and every transaction that happens. So let's say today you want to be a maintainers, then you can request a journal entry to the network and download it, you can then see its contents.
However you can not find out who the owner is because the data stored is Bitcoin address (imagine account number), without name, address or other personal information.
When Andi sends Susi 1 Bitcoin (BTC), then an instruction will be sent to the entire network that holds the copy of this journal. The instruction is to move 1 BTC from Andi (reduce) to Susi (add). After this instruction runs then the entire journal in the network will get an update.
To prevent counterfeiting of instructions the network requires evidence that the instructions for moving 1 BTC are from the original owner Andi. This is the job of a private key that belongs only to Andi. Through the process of electronic computing, the network can verify this transaction and prove that indeed Andi is sending instructions.
Unlike signatures in checks that can be faked continuously, this private key will generate different signatures for each transaction. Subsequent transactions will result in a signature (marker that this is the original owner) is different.
