I have a young hamster and he doesn't like human (mine??) hands.
He doesn't mind taking the treats, but otherwise tries to avoid them like a plaque. Even if I handle him, first thing he usually does after being let out is cleaning his fur.
I still scoop him out, to play in a play area or just to climb over my lap/arms. I don't think he will tame completely.
Somewhat I understand it as a pert of his personality.
Mine doesn't come out much of his hut during daylight - just for some food/drink/toilet, unless the fresh food is given.
Hope your hamster will settle soon.
