Chess opening/tricks for 500 elo

What is the point of learning tricky openings?
If it works, you win by them not being aware. If they are aware they usually have a way to counter and you end up in a worse position. Eitherway, it doesn't seem to be beneficial for longterm chess development.
That said, I guess Scholars Mate and Wayward Queen are the ones I've heard of as a beginner.
Not really a trick, but the Fried Liver attack is good.
It can be played against the two knights defense and it goes like this:
1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 (white is threatening to fork the black Rook and Queen) 4... d5 5. exd5 Nxd5? 6. Nxf7!? Kxf7 7. Qf3+... From here the game can continue in multiple ways, but it is a very strong attack that white has going.
The good thing is, you are not in trouble in anyway if you end up playing against the two knights defense mainlines.
I have had multiple very fun games with this opening.

Best trick gambit one of your center or bishop pawns to gain a tempo or two in any opening and your opponents are likely to be confused

Kings Gambit, Vienna Gambit, Queens Gambit
These are genuinely good gambits but opponents aren't that likely to be confused.

Just learn something that isn’t scholars mate really. It used to be ok but too many people know about it now.

Openings and trick won't help you.
Chances are you already know more about openings than about any other part of the game. The thing that you should concentrate on is to play well and not make elementary blunders.
Take this game:
On move 10, your opponent threatens mate in 1, and you defend against it. Next move the opponent threatens with the exact same mate again, and you let him do it. In a daily game with almost unlimited time to think.
Don't do things like this.

Ooh, I love playing chess! Some tricks I like to use are the "Fool's Mate" where you move your queen and bishop out really fast to try to checkmate your opponent's king quickly. I also like the "Scholar's Mate" where you move your queen and knight out to put pressure on your opponent's king. And the "Italian Game" is a fun opening where you move your pawn and bishop out to control the center of the board. Remember to have fun and try new things!

There is no Knight involved in Scholar's mate. At least no Knight from the white side who are delivering the mate.
What you are referring to as Fool's mate is actually the Scholar's mate.
Fool's mate is a mate delivered by black and there is no Bishop involved in it.
The Italian Game is 1. e4 e5 2. Nf3 Nc6 3. Bc4...
