I've cycled through the 100 levels many times. (I'm probably on about level "750", I think.)
Fortunately there is absolutely no difference - nothing whatsoever happens.
There is absolutely no difference at all.
One way to think about it is simply that they don't show the first digit of your level.
So, level 312 is just shown as 12, level 941 is just shown as 41, 182 is just shown as 82, and so on.
Nothing at all happens each time you go through 100 levels. You absolutely do not lose anything or change in any way.
