Does a ripped cd onto a digital format sound better than the cd played on the cdp

There is a good chance it could in many cases. 

Not a dumb question but one which cannot be answered definitively since the changes you will hear may be less about changing digital bits but rather more about how those bits are processed and the equipment they are played through.
As mapman indicated, it is likely you will like the result but that could be because the playback parameters can be changed depending on the file format and player used, as well as consideration that many of today’s servers have no moving parts to create noise.  I went from a pretty high end CD player to a Mac mini server, ripped my CDs and never looked back.  While I will not say the mini set-up sounded better than my CD player, it certainly didn’t sound worse and the ball keeps moving forward.  Switching to a dedicated, purpose-built server was a step forward as was switching to Roon and separating the server core from the endpoint, or renderer.  Roon and hi-res Tidal sound great in my system.

Ideally it will make no difference.
But, if you are going to use USB, with asynchronous playback, then it may, if only because your DAC will control the clock.

I think the difference would normally be small, especially with modern DACs.

Better to focus on important stuff like room acoustics, or fancy headphones.

If you're comparing the analog outputs from a CD player to a DAC that is receiving digital audio data from a digital streaming source like a computer or network streamer, then the two primary aspects that could result in a difference are the reliability of digital data transfer and the quality of digital-to-analog conversion.

For example, a CD player with a poor optical drive may end up reading errors during playback. Some deeply technical computer hardware review web sites and forums will analyze optical drives for error detection and data read reliability. Whereas if you rip data to a digital file, you can check at that time that the data read was correct, even going as far as comparing the file data to other people's file data. And then reading the file data and moving it around becomes very reliable.

Digital-to-analog conversion is fairly well covered in online discussion, audio equipment reviews, and measurements.

The counter argument against digital transmission into a DAC is that a digital audio signal like S/PDIF may be subject to incorrect interpretation or timing inaccuracies. Versus a CD player where its internal I2S data stream will go straight into an internal DAC with both parts driven off the same master clock, or clocks that are tightly coupled.

There can also be other considerations at play, such as how AirPlay transmits all audio data at 16-bit/48kHz, Wi-Fi reliability issues, etc.
