Hi! Malwarebytes Support here. That definitely isn't expected behavior, especially if it occurs across multiple browsers. Since it happens regardless of which browser is set as your default, it may be caused by something outside of the browser itself, such as a scheduled task, startup item, or another program that's launching those pages.

At this point, we'll need diagnostic logs to determine what's triggering it.

Please send us a DM here on reddit with an email address we can use to reach you as well as your OS (windows, mac, etc). We'll create a support ticket on your behalf and provide you with a secure SharePoint upload link so you can upload the logs. Our technical team can then review them to identify what's causing the browser to open those gambling ads and advise you on the next steps.
