Buying a iMac

So I'm not really that good at computer stuff but I'm really itching to play the sims again. I don't have the money to buy a proper gaming setup so I'm thinking about buying my sisters old iMac, would it be able to play the sims 4 with expansion packs and other gamepacks smoothly without bigger issues? Below are the specs:

iMac (Retina 4K, 21.5-inch, late 2015)

Processor: 3,1 GHz Quad-Core Intel Core i5

Memory: 16 GB 1867 MHz DDR8

Graphics: Intel Iris Pro Graphics 6200 1536 MB

It has the macOS Monterey

Somebody with better understanding of these, please help!
