I'd feel pretty lucky over getting a 1 in 36⁶ = 1/2176782336 chance of getting that combination assuming alphanumerical characters. If you imagine the ticket dispensing machine is black then it won't be racist. Next time make sure to examine closely the exterior hue of the ticket dispensing machine to make sure it's not racist. I'm black so next time I could also deliver you the ticket by hand in case it has the 1/2176782336 combination on it. I could also read it out for you to make sure it's coming from my mouth and not the ticket dispenser. Or I can get Google Assistant to read it out for you with Google WaveNet African American Male Voice #4.
