Uh, yeah, pretty much. But that's not the only thing.
And that's why the character is fictional, and not realistic. A lot of real people have lost their parents at a young age or been through other terrible tragedies. How many of them have taken to dressing up as an animal-themed vigilante? That's right, none, because you'd have to be pretty damned bonkers... no matter how much money and resources you had.
And that's just on a surface level. For a person to be as fundamentally driven and focused as Batman is on fighting crime they would absolutely be sociopathic and unable to function in other areas of their lives. If Batman were realistic, he'd be more like Rorschach... a loner who is so driven by his quest for justice he might be losing touch with reality. He'd be completely anti-social, probably wouldn't even bathe, etc. To be as absolutely dedicated to a single purpose as Batman is a real person would lose touch with pretty much everything else.
And then there is the trauma of seeing and enduring the stuff Batman deals with on a daily basis. That alone would send an actual person straight to the loony bin. At best, they'd have severe Post-Traumatic Stress Disorder, which would almost surely lead to many other conditions. He would completely snap. And pretty quickly.
So, yeah... no, Batman is not the least bit realistic even on a personal level.
And that's fine. I love the character. Absolutely one of my favorites. But I know it's fantasy, even in its very notion.
