That's an improper calculation. Slight nuance but orders of magnitude difference. A better approximation is:
If a fix had a 1 in 250,000 chance of causing a different error that would result in a fatal crash then it would be worse than the 737-MAX problems.
And converse:
If a fix had a 1 in 250,000 chance of causing a different error that could result in a fatal crash then it could be worse than the 737-MAX problems.
MAX's MCAS generates way more errors than 1 in 250k. A few of them resulted in a crash.
