Yep, you're fine. There was plenty of oil in the engine by the time you shut it off.
Reminds me of one time I had an oil change and told the shop to look the vehicle over because I was going on a long trip (Detroit to Arkansas). For some reason I parked backward in the garage. Later that evening I notices some oil on the floor. Came to find out the drain plug was only finger tight. Would have been just like your situation halfway to AK. Anyway, I change my own oil now.
