Telegram, as a messaging service, uses cloud space to store its data, and once you have saved a contact on your device, the contact gets automatically saved in your Telegram contacts.
This process also works vice-versa, which means that any contact you save on the Telegram app gets saved on your mobile contacts as well. But, you can easily change this setting and turn off the Sync Contacts option in the privacy setting of the app.
