Confused about the crop factor in APS-C sensors

My camera is a6400 which has an aps-c sensor. If i want to shoot at 50mm, does that mean my lens should be 33-35mm to compensate for the zoom factor?

I've read about 50mm and wanted to try it myself to get my own experience with it.

I was about to buy a 50mm prime lens, but would also that mean it's actually 75mm view and not the real 50mm?

Please help a newbie out to understand this part. 🙏
