How to Pronounce Arabic like a Native: Letters daal, thal, seen saad, daad, thaa د ذ س ص ض ظ

I've been looking up Arabic videos and resources for just a few days, but the distinction between these sounds is something I still don't fully understand, and I can't hear any difference either. Do you put more pressure on the tongue, do you tighten the back of the mouth or throat, or anything else?
