def task_func(source_directory: str, target_directory: str, pattern: str = r"\d{4}") -> int:
    """
    Moves files matching a specific regex pattern from a source directory to a target directory.

    Parameters:
    - source_directory (str): Path of the source directory from which files will be moved.
    - target_directory (str): Path of the target directory to which files will be moved.
    - pattern (str): Regex pattern to match filenames.
                     Defaults to r'\\d{4}' to match filenames containing four contiguous digits.

    Returns:
    - int: The number of files successfully moved.

    Requirements:
    - os
    - re
    - shutil

    Note:
    - If source_directory does not exist or is not a directory, this function returns 0.
    - If target_directory does not exist, this function will create it.

    Examples:
    >>> os.listdir('/path/to/source')
    ['1000.txt', '1001.txt', '1002.txt', 'not_a_match.txt']
    >>> task_func('/path/to/source', '/path/to/target')
