here is a short version:

the lightning network is basically a series of BTC wallets. each LN Node is a wallet that holds some btc. the operator opens a node and places BTC in it.

to send Satoshi, the lightning network notes down transaction between lightning nodes, and funds available in each node, and switches funds back and forth, without actually moving any funds.

only when the lightning node operator closes the node, the btc is finally balanced out and BTC is transferred back to the wallet of his liking.

this is how there are very low fees and it is lightning fast.

🙂 there is my five cents... 😸
