Dear @Taniya,
Maybe I could answer some of your questions in your earlier opened thread as well.
First of all, congratulations for getting a vocational training position (Ausbildungsplatz) - well done!
As long as your asylum procedure is still pending, you may just start/continue your vocational training and you are anyway allowed to stay in Germany. In case your asylum application gets rejected, you still have the opportunity to apply for a so-called Ausbildungsduldung. Please see, for instance, this thread for more information. We actually discussed the "Ausbildungsduldung" many times on this platform.
However, please also don't hesitate to get back to us with any further questions.
All the best,
Meike
