How do I begin?

Hi to all !
I read a lot on this forum and lot information are very helpful!

I have a question :

I was involved in project management in France but not as a project manager. I would like to upgrade and have a better position.

Now i live in Netherlands and I'm really interested in scrum mindset.

I already begin open assessments (scrum open + product owner open) and got 100% a couple of times

But i have doubts...I wonder if i have to begin with PSM or PSPO training. It looks like all is needed but all is not affordable for me.

I plan to attempt to a training course but is there an order in the learning steps (first PSM and PSPO in second) or it does no matter?

(I'm a beginner, never work with scrum or agile and I'm not english native).

Thanks for your advice
