What are the odds?

What are the odds foe getting a max win on a regular spin in pragmatic, hacksaw, and no limit slots? So you actually have to purchase those super scatters or such in order to actually get a max win? Eg, duck hunters. Had so many spins, but never got a 5 scatter. Even if we do purchase those expensive spins, it doesnt guarantee any big wins right? Since i did grt a 5 scatter a couple of times. One was a pragmatic slot and 1 was a no limit slot. But they paid me nothing, no limit was $0 which was fucking bullshit. And the pragma one was just $20. Bear in mind, my spins are $1 spins.
