Liquidity swap potential rewards

Hello, I've been trying to read up on how liquidity swap works and what the potential risks and rewards are. From what I understand, you lend your coins to an automated market maker that then provides liquidity to the market, collecting trading fees that are split between you and the AMM.
I've read about the risks (bugs in the system, slippage, impermanent loss, fees), however the rewards are not quite clear. I see a % total yield number, but is that number the annual yield based on the daily movement? What does it represent?
To make a specific example, if I wanted to put 1000$ of BNB and 1000$ of ADA in this pool:

Total yield

22.65%

Rewards
9.51% BNB
Trading fee
13.14%

What would my yield in a month be if that yield remained stable and the BNB to ADA ratio remained stable?

Two more questions:

-The trading fee (13.14% in my example) is what the AMM collects for themselves, right? So that one I don't care about. Is there anything else I would have to pay when taking my money out of the pool if I added both coins in a 50/50 ratio?

-Say a technical problem arises with the smart chain and my money evaporates. Since the liquidity providers on Binance use their own smart chain, is Binance covering the losses? I've read an article about them doing so but are they obliged to do so or is it up to their discretion?
