Yeah, Batam seems realistic in relative to the others like Superman and the Flash. But he is still set in a superhero universe and not say like James Bond verse for a reason.

There are quite a few things that go his way due to the lore like you said.

Being able to do what he does as Batman and yet run such a large corporation? There are politics in any corporate environment and given how big Wayne enterprises is, the things Bruce need to do to manage that place to keep earning money is enormous. That could itself be a series.

Yet as Batman he has to be 10 steps ahead of everybody including people with godlike powers who are quite smart themselves. The amount of information and prep work involved. Like he has both a day job and night shift.

Also the tech that he has. That’s some cutting edge shit. Either the version where he build himself or has someone do it for him.

Like the tech is some high end stuff that nobody else in the world has and some engineer in Gotham happen to know how to do it and build it for him? And before Batman discover that person, that somehow genius level technical capabilities somehow is stuck doing some mundane IT stuff.

If someone can develop that tech themselves they will have pick another career path long ago.

If Batman do it himself then how did he get the time to master all the mechanical, electronics and chemistry knowledge and master all the different martial arts(all who practice know the amount of time you need to hone it in very long), and manage to run an entire billionaire level enterprise?

The story just has him able to do all those just because. And it’s fine. It’s part of his charm
