Hubdreds of rejection for nursing ausbildung / starting as a nursing assistant

Hello everyone, I have as of today applied to over 400+ ausbildung place as a nurse but have been rejected by 170ish place and ghosted by the rest.

I searched if I should apply through an agency but could not find one that does not look like a scam in my home country and could not find people recommending ones based in germany.

So my question is: Is it more likely to get accepted as a nurse assistant, do the year then transition to a nursing ausbildung? is this accepted by employers to know i do not care about being an assisant and just using it as a step to apply for another ausbildug?

I am very interested to hear your opinions and thank your time.

Note: I live in egypt, have a b2 but can not get get across the anerkennung of school certificate and suspect this might be the reason for my rejections as stated by a small number of rejections.
