PNG files do not support CMYK but you can use jpeg.
What does the printer mean by If we convert these colors into CMYK, the sticker will look with a completely different color.
Read the bit here about RGB to CMYK colour change https://www.rgb2cmyk.org/about.html
A converted jpeg using ISOcoated.icc colour profile (I use Gimp/Cyan) file attached. heart.jpg
This is the sort of colour change to expect: The printing company wants you to do the conversion to avoid customer complaints.
You should start and finish a project all in CMYK. If you do not have PS then you can use Krita https://krita.org/
edit: Just a thought: Do not open the CMYK in Gimp for other than viewing. Edit or re-export and Gimp uses RGB colourspace.

this is what it looks like now, the aim is to achieve the same result,but made with the cmyk colors
When I convert RGB TO CMYK the whole color changes?
Some RGB colors that you can see on your monitor (in particular, blue, green and all bright vibrant colors) cannot be printed and/or replicated with standard CMYK inks.
