This depends on your online poker site of choice.
A number of online poker sites also have sister sites that allow sports betting and casinos but those are generally segregated away from poker.
If you’re really intent on having a one-stop shop for online poker and casino/sports betting than you might want to take a look at an unregulated site.
Because unregulated online poker sites operate with fewer restrictions they sometimes offer a complete all-in-one betting platform with online poker, gambling and sports betting. Some sites even let you play Black Jack while you’re seated at the poker table.
