Dear student,

I hope you are safe and doing good.

IoT or Internet of Things is primarily a full system of all mechanical and digital machines which are turned into interconnected computing devices. If we have a look around our surrounding, then we can see that most of the devices are IoT based like Smart Bands or Fitness Bands , Smart Smoke Alarms,  Amazon Dash button and this list goes on.

While, Data Science, is defined as the process of obtaining valuable insights from structured and unstructured data by using various tools and techniques. Some of the techniques practiced in data science include data extraction, data analysis, data mining, and data retrieval, to produce informative results.

In simpler words, IoT is about simultaneously collecting and processing data to make real-time decisions whereas, data science is more into collecting and accumulating huge data for analysis afterward.

So, they work on the same thing but differently and it would be somewhat difficult to represent that in the form of percentage.

I hope you got your answer.
