"Betcha" is short for "bet you" which is used to show that you are certain or confident about something being true. Ex: I betcha tomorrow they will be sold out. "Betcha" can have a different meaning when used in the expression "you betcha". This is another way of saying "yes" or "sure". Ex: "Can I have some water?" "You betcha!"
