He's still fairly young, and even though yeah it will get him used to it at younger age, which is good, he'll still be a bit timid and jumpy. Get him used to your hands, feed him treats, rub your hands in his (clean!) sawdust/bedding... so you don't smell strange, and lightly stroke him. He will probably nip, but it won't be hard, but if he does, just jerk your hand back, so he won't like it and know that you don't. Then, if you're still nervous about picking him up, hold him in a blanket or wear gloves, but, yeah, it is good to get them used to you when they're young!

My newest hamster was very shy, but once you spend time with you, it'll just click and he'll love you!!
