How come professional hackers can't just add any amount of number into a bank account?

Your mom has a jar of cookies on the counter. They are all for you, but your mom has them locked up for safe keeping so your older brother doesn't take them. She has a bunch of padlocks on it too.

One day, you figure out you can open the padlocks, and that once you have the jar open, you can touch them with your magic wand and make there be as many cookies as you want. The catch is, you can only make the cookies appear inside the jar. To get the cookies out, you have to get your mom to give them to you, or transfer them to another jar, kept by your dad.

Now, Mom knows there were only 10 cookies in there when she left for work this morning, so she's going to notice is there are suddenly 100 cookies there. And Mom talks to Dad all the time (seriously, she like texts him a million times a day at work while he's in meetings) so Dad knows there's only 10 cookies there. If you suddenly try to transfer 100 cookies from Mom's jar to Dad's jar, he's going to notice.
