This reminds me of a self-working trick I saw online in the 90s.

The website shows you a hand of 5 cards, and asks you to pick one card and stare at it intensely. It claims it will read your mind and guess the card. When ready, you will click a button, and 5 new cards are shown - 4 random cards plus the card you thought of.

...

The trick is that the same cards are shown as before, but in different order. Most people only focused on the one card and don't notice that the rest of the cards are the same. It sounds very simple, but it worked on me and all my family members, at least the first time.

I have seen the same concept where they show 5 cards, ask you to choose one and then click the button.

Then it shows the other 4 cards, with your card removed.

In reality of course it’s a similar set that contains none of the same cards.

Do you remember what site it was on? It sounds super familiar.
