Would it be worth it?

I am 18 years old from a third world country, currently a student in united Arab Emirates and I am planning to learn German till b2 to apply for an ausbuilding specifically for mechatronics engineer cause I have passion for cars and also I hate studying something I don't have passion for i.e university. I have recently finished my A1 level.

My question is would it be worth it? Are they recruiting someone who is from third world country? Also I have heard you can only get a contract through agents only, which in my case seems expensive.

I know that the first 3-4 years would be harsh bcz of low salary but after I get my diploma will it get better?

Thank you.
