Can I sell data that is displayed on a betting website in my own api?

If I was able to scrape the odds, events, date and other things from a betting sites public website, where anyone can access the information. Would I be able to sell this data in an API?

The betting sites would be the 10 most popular betting sites in the UK, and I would be getting information on all the matches in the biggest football leagues.

Could I be sued if I start selling this data, or am I allowed to as it’s publicly accessible and the only thing they can really claim to own are the odds, if they can even do that. The data would be sold as an API service where members pay monthly for a certain number of requests to the API.
