Is try catch required for simple CRUD operation in Laravel Eloquent

I am less familiar with error handling and my question is different from usually I asked so please guide me if I am wrong. Sample of my CRUD operation:

User::where('active', true)->get(); // index method

User::where('role', 'admin')->first(); // show method

User::create($request->validated()); // store method

$user->update($request->validated()); // update method

$user->delete(); // destroy method

I have a project of Laravel containing following things:

1. One database (12 - 15 tables)
2. Model (6 - 8 Models)
3. CRUD Controller (for each model)
4. View (index/create/edit for each model)
5. Middleware ( 5 - 7 user roles)
6. FormRequest (store/update for each model)
7. Observer ( for each model to clearing cache items)
8. Policy ( for each model to check user based role permissions)
9. Event & Listeners (default/in-built)
10. Without API & external package installed

Do I need to enclosed try/catch block to each part of my CRUD operation ?

try {
    User::where('active', true)->get(); // index method

    User::where('role', 'admin')->first(); // show method

    User::create($request->validated()); // store method

    $user->update($request->validated()); // update method

    $user->delete(); // destroy method

} catch (\Throwable $th) {

    return to_route('home')->with('alert', alert('Error!', "Something went wrong",'error'));

}

Or, if something goes wrong in the DB, Laravel will handle it.
