What ow93 is saying has merit but I can cite one occasion when it made no difference.
Back in the Super Sportsman strike year (1972?), Lincoln eventually became the series' Saturday night home. There was a driver (Ron something?) whose family literally lived on saltines, peanut butter and water the previous winter so he could make his dream of owning a Super Sportsman a reality. He served his two rookie weeks starting in the rear of his heat and the consy. I'm not sure, but I don't think he made either feature. Then on week #3, he got to start on the pole. I can't recall if this happened in his heat or the feature, but coming down the frontstretch to take the green flag, he got crossed up and what seemed like the entire field ran over him. He was okay but his dream car was junk and I never saw him at the races again.
There's no substitute for experience but about the only place to get any experience with a race car is at a racetrack.
