Did I pay this 5000+ sats fee by myself?

Might be a stupid question.

Want to do p-2-p but don't want to do something stupid by accident and lose my security deposit on Bisq. Was forced to use an exchange.

I sent BTC from the exchange to a wallet.

An app in Watch-Only mode for that wallet shows "Transaction Confirmed 2/6"

The amount sent from the exchange is $0.68 higher than the amount displayed as in possession on the watch-only wallet. This loss is just the network fee which I was already warned about. That's fine.

The problem is, before it said "2/6 confirmations", it said there was another fee of over 5000 sats, and that, in USD, is over 10% of the amount I had sent. Is that representative of the entire block being mined, so other senders online right now are sharing the burden of that 5000+ sats fee with me, and my share of the burden was only $0.68? Or have I lost 5000 sats from somewhere (the exchange, the receiver's wallet once we reach stage 6/6, something else?)

On mempool, something that anyone can access, the same 5000+ fee is displayed. This suggests it's shared.

The receiver's address is segwit bc1, 42 characters.
