As FaeryBee said, it takes A LOT of time and patience to tame a bird and get them to trust you. Also, keep in mind that since birds have individual personalities, not all Budgies will have an interest in becoming a “tame” bonded buddy with a human.
My current budgies were both handfed and human raised for about the same amount of time, yet my female remains more trusting and will step up when she feels like it, while my male won’t. He’s not “wild”, he just had his limits and boundaries with humans.
Same with one of my handfed hand raised parrots.. he just has his very strict boundaries with me, unlike another parrot who is extremely cuddly (and a closely related species). The standoffish one probably even had more consistent early handling too, but still didn’t guarantee anything.
I also had a standard budgie who eventually became “not wild” yet did not want interaction with me. Although he’d step up when he knew he was having out of cage time.
Hopefully yours will show interest in befriending you and your family after some time
. But if not, don’t get discouraged. Just know that not all birds have an interest in the human bond
I’m mentioning my own Budgies and other parrots as an example how totally different they can be as individuals despite similar backgrounds as chicks.
