I'm a little over 100k and most times I've broken spokes is when I have abused the bike in some way. Jumping off stuff, crashing through a massive pothole at 30mph, too much power (>1000w) and a lack of maintenance have all caused me broken spokes.
I have also had the odd old spoke go pop, mostly when they have been well used and are rusty.
In short, you'll be fine.
