When it comes to taming, let the hamster set the pace. If they don't want to interact at the moment, back off and try again later.
Treats go a long way to getting them used to being handled. Use healthy treats like sunflower seeds or mealworms or sugar free cereal puffs (my hamster's favorite
)Put some treats on your flat palm and fingers and let the hamster come up to take them. At first they'll probably stretch their necks to take treats without touching you, but eventually they'll start to put their paws on you to get to them. You can trail treats up you palm and up to your wrist to encourage the hamster to climb onto your hand. The idea is to associate your hand with positive things, like yummy treats and gentle petting
the important thing is to be patient; we're big and scary and it'll take time: sometimes weeks or months to break that association.
It sounds like your hamster is already fairly comfortable with your presence, especially since you started so quickly; generally you want to give the hamster 2-3 days to settle in without human interaction. But if your hamster is receptive to it and didn't seem distressed, there's no harm in starting earlier
