There is nothing wrong with ambition if you can back it up. The world is full of people who lack ambition, have no direction and can't lay out their career ambitions in an interview or who have a view of what they want but zero idea how they plan to get there or why they think they are capable of getting there. It matters little how ambitious you are, it matters greatly how and why you feel you will achieve those ambitions and this would be exposed in an interview. It is a fine line between ambition and unrealistic self elevation, so you need to think about that. Expereince counts for a lot, but if you are up against someone who has 20 years experience and no ambition and you are ambitious with a clear direction and solid common sense that allows you to be developed then that puts you in a stronger position in my book.
University qualifications are what allows an employer to differentiate and categorise, it matters less as you progress and get quantifiable, relevant experience and you need to be careful not to fall for the view that a good university experience and certificate makes you special or that a year internment makes you experienced in work. You need to think about why you are a better prospect than the other 10 people who might have the same qualifications and much more experience as if you can't build that discussion your ambition is worthless as it's hot air and conjecture. Build a picture, lay out your first 90 days and show your knowledge of the company, their culture, their way of working and where you believe you will bring value and you will instantly kill 80% of the other people you are up against.
