Some people who track a lot are on stock suspension, does that make them a ricer? Then there are also those who track a lot that are fully cages and on racing suspension.
You know a lot of ricers though. You must be the only pro driver in your region. 
I highly doubt the two types of people you mention are ricer. For one thing ricer only street race. Ricer does not equal stock car or stock suspension. No ricer is the art of modify the car badly. For example: fart can exhaust, cut springs or cheap china suspension, car lower too low to be able to successfully navigate through speed bumps, aluminum control arm that don't do squat for the car except maybe save weight, car with stickers but don't actually have the parts or cars with too much stickers unless its a sponsor race/show car. Now don't tell me every hmong people has a sponsor race/show car. You know it when you see it. Stance nation = 2015 ricer.
Knowing ricer does not = one becoming a pro driver. Base upon your logic I must be Pro at everything since I know a lot of people who do other hobbies at a amateur level. Plus going pro does not equal being good at it. Any idiot can go pro in any sport and take last place. The only Pro I'm aiming for is making dough. Yes I'm talking about pastry, doughnuts, cakes. LOL.
