I won't say they DON'T matter but they aren't in and of themselves disqualifying.

I had too many speeding tickets in college and actually had to get them waived by the ROTC. I was told that one more ticket and I would be kicked out.

You can go get your legal records and see what tickets show. Every airline pilot does this prior to an interview. That might help as not all of them may still be on your records.
