> the relief of finally remembering the name felt like, well, hitting a jackpot

I understand the joy of success but I fail to see how this is gambling. I could have an equivalent conversation with a friend (more likely about a movie in trying to remember than a painting, but still) and get the exact same type of iterative “no, not that one, it was more like X” and feel elated when my friend finally realizes I’m taking about a scene from Hot Tub Time Machine.

This isn’t gambling in any meaningful sense.
