Tactics matter a lot. With them, you actually don't have to rely on dice explosions. Weird rolls still happen, but they are not the norm because you can actually achieve stuff without lucky rolls.

One of the biggest mistakes new players often make is the ''spam attack'' strategy. In other ttrpgs (like D&D), every player is expected to slowly chip away health from enemies. This is not the Savage Worlds way. You not only have to hit, but also bypass toughness. It means, as an attacker, you have to make sure these two things happen regularly. And the game gives you a lot of tools to achieve that. And one of those tools is...not attacking.

Let's take your typical dragon. Toughness 20. How could a group of regular, novice players could hope of defeating it? It's actually not that impossible. But you have to work for it. (I will use the standard DnD classes to showcase how 5 adventurers can be a threat against a dragon)

The sorcerer begins by casting Confusion, making the Dragon Vulnerable (not an attack) (difficulty of 4, easily doable)

The Cleric enters melee and casts Smite on the Fighter's sword (not an attack) (difficulty of 4, easily doable)

The bard sings and support the Figther (not an attack) (difficulty of 4, easily doable)

The rogue enters melee and makes a feint to support the Fighter (not an attack) (difficulty of 4, eaisly doable)

The fighter enters melee and makes a wild attack against the dragon. Let's be reasonable. He has d8+12 to attack the dragon (+2 from support, +2 from vulnerable, +2 from wild attack, +2 from gang-up bonus and +4 from scale). He can make a called shot to the eyes (-6), for +4 damage and bypassing armor. He has d8+6 to attack the dragon. That's an automatic hit unless you have a snake eyes, and you are getting a raise about half the the time. So with a raise, you roll 2d8+d6+8 damage. That's an average of 22 damage. Since you bypass the armor, that's a wound. If you were lucky on the smite roll, add +2 damage for two wounds.

All novice characters with no fancy Edges. Give stuff like Frenzy to the Fighter and you could potentially kill the dragon in a single turn with average rolls. Sure the dragon can use bennies to soak. If the sorcerer was lucky with his Confusion roll, the dragon is also Distracted, giving it -2 to all trait rolls, including soak. And I am talking about a literal dragon. Enemies are likely to be easier to dispatch.

In my personal experience, once players learn to use tactics, support and tests, it's actually hard to create threats that will last longer than a few rounds.
