Default Holding on to an atmosphere

I've been listening to last years shows about the planets and there was talk about being able to glue wings on a person and fly on Titan due to the low gravity and thick atmosphere. Well, if the gravity is low, how can it hold onto any atmoshpere at all? How does something get and keep a "thick" atmosphere?
The same kind of applies to Venus. How can it's atmosphere be so thick and heavy to create the pressures it has?
