The dictionary defines information as: Knowledge or facts learned, especially about a certain subject or event

And data is defines as: Facts that can be analyzed or used in an effort to gain knowledge or make decisions

Data and information can have specific definitions and differences in various technical contexts. But colloquially, they are often used interchangeably; or sometimes we define data as the raw knowledge, and information as the additional knowledge inferred from the data.

Data and information are philosophical concepts, they do not have a tangible presence or consume physical space. However you can't store or convey information without some physical medium on which to do so. Data in a brain requires neurons. Data in a book requires ink. Data in computer science requires electricity, or magnetism, or bumps on a polycarbonate surface, etc.

To "use data" doesn't make literal sense in most cases, data as a concept cannot be physically "used", and even as a physical representation often the mechanisms used allow the data to be "consumed" in a way that does not deprive anyone else of it - essentially a copy of the data is communicated.

But when you say "using mobile data" it's clearer what you mean colloquially. In this sense, you are "consuming" a portion of your allotted mobile data plan. Or in other words, it costs money to run a mobile network; you've paid for the ability to send and receive a certain amount of digital data using the provider's network, so performing an activity like browsing web pages or watching YouTube videos counts towards that data usage. And if you go over that limit your access may be blocked, slowed, or incur additional charges. The "usage" and "consumption" occurring here is in the sense of your contract only allows a finite amount of data transmission, it's not like you are physically taking electrons away from YouTube and they might run out. "Using data" is just the shorthand term we use to describe this.
