Is gift fusion actually random?

[Ekimmak]

I know that there's those super gifts that take two specific gifts, but that's not what I'm talking about.
I fused two gloom gifts, for my Sinking team MD run. Got White Gossypium.
Didn't want it. Sold it at the next vending machine. Got to the next rest stop. Fused two more gloom gifts.
Got White Gossypium again.
