Did I just witness one of the rarest events in Minecraft history?

My game started off with a decently lucky streak, spawning near water melons for a good food supply and then was able to find easily accessible iron, then coming across a desert temple, then finding a lava pool. Now, since I didn’t yet have a bed, I built up close to it so I couldn’t get killed by mobs. Then, I look into the distance, and I quite literally see a Parched and an Husk both mounting a camel at the same time. I know this is true because it came very close to my tower where I was able to directly witness it before it got pushed into the lava pool and burned. Is this a glitch or a normal event?
