Essentially yes. InDesign, when exporting to a press-ready format, will convert RGB images to CMYK based on your assigned color profile settings.

So theoretically you could use RGB images in everything and allow Adobe and your color setting to handle all conversions. This will work.

However, in many cases you may want to verify color in an image when switching gamuts. If you have a bright, vibrant, RGB color within an image which is outside the CMYK gamut, the automated conversion will do what it can -- which may or may not be correct for that image.

It all really comes down to the level of control you want over your print production files. Automated conversion has been around for a while. However, if you really want to check color and be accurate with conversions you pretty much always need to verify colors after the conversion. In many, many cases converting from RGB to CMYk takes some "tweaking" to get colors correct. This can be especially true for many skin tones.

For my money, I manually convert RGB images to CMYK and then color correct as needed. I don't allow the Adobe automation to convert color spaces for me. "By the numbers" is almost never as accurate as a human eyeball.
