I think generally the personal discipline, and personal psychology, and emotional-dynamic aspects of both poker and trading are very similiar.
World-historical traders such as Mark Minervini (interviewed in the book Stock Market Wizards) and others strongly suggest poker play as important training for traders.
I therefore conclude that a successful poker player, who by definition must develop keen discipline, emotional control, judgement etc, is likely very much predisposed to a successful trading career, as compared to any randomly selected non-poker candidate.
A major trading concern reportedly uses Sklansky's books and poker playing in their trader training. You can examine information on that here:
