Not necessarily. Racking to secondary can often increase the risk of introducing an infection, but if your sanitation practices are sound, you should be ok either way. Pretty much everyone is bound to get an infection sooner or later. It may take 10 batches, it may take 10 years. I haven't had one yet, but I'm sure it will come one day.
