WazHack, as a rogue-like, has a great deal of luck involved. That is the nature of the genre--a careful balancing act between the influence of luck and of skill. Initially, after some "unfair" deaths, you will think the game is all about luck. This is an illusion. WazHack does involve quite a bit of skill, but in ways that are not apparent until you have braved the depths repeatedly. You will die, often. You will make mistakes. But unlike a lot of games, growing from those mistakes is not an automatic, subconscious affair. As the great yoshimitsu once said, "overconfidence is the greatest enemy".
How then, do you reveal the skills involved in WazHack?
Easy. You think. Every item carries a risk, and managing those risks is something learned by practice... By glorious, stupid deaths from a wager failed. Do you try on every piece of equipment you find? Bad move. You just equipped a cursed -3 helm, sucker. Good luck getting that off. Do you equip every amulet or ring you find? Sorry, that was enchanted with polymorph. You are now a rat. It seems random, and to an extent it is. But through play, patterns emerge. Starter pets growl at cursed items as they approach. Traps on the ground could burn, inflict sleep, teleport... Why not jump over? Hm, there's a door here... If I open it, enemies spawn. But if I defeat them all and check once more, I am rewarded.
So yes, WazHack is a game of chance. Every rogue-like is, to varying degrees. But it is also a game of skill. Don't forget it.
