the cost to mine is a separate cost to the lost money in trading.

The cost to mine is somewhat "fixed" - and tbh, a miner would not choose to lose money to mine, but just stop mining if their source of electricity is too high for profit.

The trade losses are speculative losses, and it comes from the "wins" that someone else on the other side of the trade.

Yes of course. But the point is that it costs a lot to mine, and that is subtracted from any profits made.
