How to not fall over on a bike?

How can one avoid falling off a bike while riding? Are there any specific techniques or practices that can be implemented to ensure stability and prevent accidents? Are there any common mistakes that riders tend to make that can lead to falls, and how can these be avoided? Additionally, what role does balance, posture, and the use of brakes play in maintaining stability while biking? I'm eager to learn more about how to safely navigate the roads and trails on a bike, and any advice or tips would be greatly appreciated.
