Question

Answer

"I'm outta here" means "I am going to leave now."  It is very informal and slangy.  You can use it in an urgent situation -- "This place is going to explode.  I'm outta here" -- or you can use it just to mean "It's time for me to go."  Example:  "It's getting late.  I'm outta here."

"I gotta get out of here" is also informal.  You would use it when there is some urgent reason to leave.  Examples:  "There's too much cigarette smoke in this club.  I gotta get out of here."  "The cops are coming.  I gotta get out of here."

Answer

You are right. "I'm outta here!" means "I'm getting out of here"
