I often hear that wood glue is stronger than wood but if you glue end grain to end grain and then apply stress it will break at that connection. What gives? I’m probably just stupid.

The caveat is that wood glue is stronger than wood if used correctly. Wood glue works best gluing grain to grain. It’s easy to split wood along the grain because the natural bond between the fibers is not that strong and it’s that bond that the wood glue is great at replicating. In your example the wood glue is being tested against the strength of the fibers rather than the bond between them

Also it usually won’t penetrate into endgrain to get a good bond- lots of YouTube videos on guys like Mathias Wendell and others strength testing different joints and glue joints! I recommend many diy’er to watch some so they have a comparative understanding of different basic construction methods - then you can pick appropriately
