Very low unless you have a strong connection to a program, unfortunately i would assume many programs filter out step 1 failures

0 chance if you failed step 1 three times. I'm sorry. You would need to be one of those guys spending 8 years as a fellow at UMiami to match.

I think 3 attempts on step 1 means there is essentially zero chance. If you failed step 1 once, there might still be a shot. Some programs last year matched people with step 1 fails, but you need to have a crazy strong advocate

Virtually all programs will filter out a step failure
