Welcome guys, i am a beginner in creating ambient music.I've watched some tutorials
but it still hard to find a good samples (can be not free) for my projects.
Recently i found https://www.lucidsamples.com/ambient-sample...ace-sounds.html
and I’m thinking about buying them. Have anyone of you bought samples from them? Is it worth?

Try http://www.freesfx.co.uk/
Or add keyword "royalty free" "ambient royalty free" when searching free stuff.
