No, Italo and ItaliaRail are completely different entities and serve different roles in the Italian rail system. Italo (officially Italo - Nuovo Trasporto Viaggiatori) is a private train operator that runs its own fleet of distinctive, high-speed burgundy trains. It competes directly with the state-owned Trenitalia and only serves major cities like Rome, Milan, Florence, and Venice. ItaliaRail, on the other hand, is a third-party travel agency/reseller that sells tickets primarily for Trenitalia (the state-owned operator) and sometimes other European lines. ItaliaRail does not own or operate any actual trains; it provides a user-friendly, English-language interface specifically designed for North American and international travelers to book Trenitalia tickets easily. If you buy a ticket on ItaliaRail, you will be boarding a Trenitalia train (like the Frecciarossa). If you want to ride an Italo train, you generally have to book directly through the Italo website or a multi-modal search engine like Omio. In short: Italo is the train company, while ItaliaRail is the ticket shop for its competitor.
