Is it wrong to add elements into a java list, with parallel stream?

Is it better to use some of thread safe collections ? Scope of the question is only the generation and adding of elements into the list.

public List<BankDetailsDTO> generateBankDetailsDTOs(int amount) {
    List<BankDetailsDTO> result = new ArrayList<>();
    IntStream.range(0, amount).parallel().forEach(index -> {
        result.add(new BankDetailsDTO(bankDetailsDTOCounter.getAndIncrement(),
            faker.company().name(),
            faker.finance().iban(),
            faker.finance().bic(),
            faker.finance().iban()));
        });
        return result;
    }
}

Change it to:

    public List<BankDetailsDTO> generateBankDetailsDTOs(int amount) {
        List<BankDetailsDTO> result = IntStream.range(0, amount).parallel().mapToObj(index ->
            new BankDetailsDTO(bankDetailsDTOCounter.getAndIncrement(),
                            faker.company().name(),
                            faker.finance().iban(),
                            faker.finance().bic(),
                            faker.finance().iban()))
            .toList();
        return result;
    }
