Both Gasoline and Kerosene are pretty flammable and should both be stored with caution.
However Gasoline is much more flammable than Kerosene is and it's easier to get gasoline set on fire than it is Kerosene.
Gasoline has a lower flash point at which it can be ignited whereas it takes a higher flash point to ignite Kerosene so Kerosene is safer to store and use than Gasoline.
But still you should keep the kerosene away from flammable sources or flame when storing it.
