thank you for reaching out to the Wefugees community and for your question.
Supposing that you hold a greek residence permit and have a valid passport, here are some suggestions:
1. You could apply for an apprenticeship visa via the German embassy or consulate to do a triennial professional training. Here you can find further information: https://blog.ausbildung.de/apprenticeship-in-germany/
2. If you've already finished an aprrenticeship or graduated from university, there is an option to apply for a speicialist visa. There are two different kinds. The first one is for job seeking, the second one is to work in your field of profession.
There are some conditions you have to comply with:
- the professional must one for Germany recognized qualification show
- German good proven knowledge of at least voice level B1
- Candidates must have their livelihood contest during the job search itself
- With a blocked account the livelihood must be demonstrated during the job search
- All candidates need a health insurance and a proven accommodation
- be secured when taking up work has the full livelihood protection by their own work

I'd recommend you to apply for a job, it will be easier to obtain a visa if you can show up with a work contract, in which your salary is specified. In this case, if your income will suffice for your living, you won't need a blocked account.
