I get probability of 0.643% assuming a mean of 23.67 blackjacks in 500 hands from an infinite deck. 2.512 Standard Deviations.
Assuming 6 decks, the precise answer is 0.529%, or once in 189.

The probability for getting a BJ in 6-deck game is 0.04749.
The expected BJ hits are: 23.7447.
1 standard deviation from the expected BJ hits is 4.7557.
Thus, the deviation of expected BJ hits (23.7447) to 12 BJ hits corresponds to 2.4696 standard deviations or probability of 0.006763 or 0.6763% (once in 147.855 attempts).
My calculations apply for all naturals the player gets no matter if they push dealer�s BJs.
