I've seen factions with +200 relations refuse a profitable trade for them and factions with +5 relations accept the same trade. An awesome mod that adds a handful of lore-friendly units to the game.

The diplomacy system is very obfuscated here. I also have never seen any evidence, that having more resources to trade increases the likelihood of someone accepting a trade agreement. So, you are generally correct in the assumption, that those resources aren't actually used by the trade partner, however not in this specific example. For all other factions, resources only increase the value of trade agreements. Note: The Tomb Kings are the only faction, which actually uses resources for their mortuary cult mechanic (edit: a similar mechanic called forging has been added for dwarves in Warhammer 2 only since posting this answer originally). So, in your example, you'll earn 620 gold per turn and no resources, while Arkhan gains 110 gold and all those resources on your side. Think of it as 'I gain this much money for exporting this and that'. The right side shows how much money they earn and which resources you import from them.
