What are my chances of getting a student visa and go to highschool in america?

Your chances for a student visa are very poor. Although you are not inadmissible due to your history of unlawful presence because you were under 18, you nevertheless lived in the U.S. illegally for almost 13 years, and you only left the U.S. recently. Section 212(a)(9)(B) may not apply to you as it would your mother, but there are over 30 other reasons why you might be inadmissible, the main one being that you have no intention of returning to Argentina once you set foot in the U.S. You probably entered the U.S. when Argentina was a part of the Visa Waiver Program. Effective February 21, 2002, Argentina was removed from the VWP. Thousands of citizens of Argentina and Uruguay came to the U.S. using the VWP, and a large percentage of them violated the terms of their admissions (as you and your mother did). If you did enter using the VWP, you never qualified for a visa previously in your life. If you qualified for a student visa now, you could only attend a public secondary school for one year, and you would have to pay the per capita cost of your education before the student visa would be issued.

Since you are still a minor, perhaps if your mother gave legal custory of you to your Uncle in Florida that might allow you to come here as his ward. I had a similar circumstance many years ago. There was a crisis in my family and no one to watch me so I was sent to family in South Africa. I'm sure there must be many instances of parents dying and their naming siblings in America as the caretaker.

you may have good chance to do so, but you need uncle to petition for you or find student exchange program, go online to hunt for answers

Your uncle would probably have to prove that he had the resources to house, clothe and feed you. At 16 you're still considered a minor in the US and you would only be allowed if an adult is willing to take responsibility for you. If it's that big of a deal to you consider letting your uncle formally adopt you. That would be one nearly ironclad way of being allowed in. If you're here when you turn 18 you'd have a better chance of being allowed to stay. Simply "planning to live" in the US doesn't carry much weight with ICE. This all assumes you were never caught when you lived in the US illegally. A deportation or detention probably means there's no chance. BTW - You're going to need to speak Spanish whether you're in Argentina OR the US. Might as well start learning.
