Yeah, MCU Bucky was almost certainly recovered by either the remnants of HYDRA (he was in their territory, after all) or by the Allies, who would've turned him back over to the SSR.
It may change a good chunk of Brubaker's mythology of Winter Soldier, but it seems pretty evident that the Russians aren't going to play a part in his evolution. And that may be just fine with Marvel/Disney anyway, as they might not want to alienate/offend potential Russian markets with "oh great, another American movie where we're the bad guys."
