Tiling on bathroom painted walls

[CrazeUK]

Hey guys. One that's probably been asked before but just want to confirm.

I have a painted bathroom. its in good condition.
Most of the wall is tiled and great condition. I want to finish the wall.

so after Googleing how to Tile. I found that a number of sources said check your paint by applying duct tape to the painted wall. leave it for a while and rip it off.

I did this and barely any paint came off.

I also tried to scrape some off by scoring it. but it's almost impossible.

so am I good to go?

thanks
