But it's also very big, and GP doesn't even specify how far of a trip they're asking about nor how small a meteorite.
"Extremely" and "very" don't cut it here. This is beyond the human ability to guess. You'd actually do at least some back-of-the-napkin math to give a real answer, and with a far enough trip, the answer may well become "Almost 100%".
And at a high enough speed, the impacts from the ~1 hydrogen atom per cm^3 in interstellar space become a major problem.
