To add to this:
1) Go into the Calendar app and then hit "Calendars" on top. Uncheck the "my calendar" box then save by hitting "done."
2) Go back into Calendar and hit the "+" to add event. Switch it to the Gmail account instead of "my calendar" and add a test event.
3) Go to the test event and delete it (or leave it if you don't mind).
4) Go back to the calendar app and add an event. It should now default to google instead of the samsung one from here on out.
Note: You can switch the prior events created by the default samsung app by going into them and switching the calendar to the gmail account. I would do this prior to doing the above steps to avoid repeating them.
Hope this helps anyone who finds it!
