So I recently assembled my new rig after four years of waiting, and I mostly play Rust but only use about 60% of my system during those sessions. Is that typical? My monitor is 144Hz, but it stutters at around 100fps due to the load. If this isn’t normal, what steps can I take to fix it? I’m not used to dealing with this since my old PC was quite unreliable.

100% usage is detrimental to everything. If they consume less, that's acceptable.
If you need 144hz, reduce the details (Ultra is mainly for screenshots)

I already run at low settings for better visibility, but I'm 99% confident that using it at full capacity won't harm my PC. I believed the issue was overheating.

You might prefer your computer to run without being completely busy. If only a small portion of your GPU and CPU is active, it creates a limitation and prevents you from achieving the maximum performance your device could offer. Ideally, both should operate near full capacity for optimal results.

Other games will never achieve optimal performance either.
Some games lack efficiency entirely.
You don’t need full CPU power at 100% to begin a task—just the main thread should be engaged.
A single render or tasks thread can quickly reach maximum usage (85-100% of one core/mainthread), which may reduce GPU utilization or cause instability.
These issues can stem from poor design, bad optimizations, or problems with threading that aren’t immediately obvious.
Certain games simply won’t work well across all hardware setups and expectations.
Rust is recognized for not fully leveraging hardware capabilities.
That’s why it’s wise to look into any game and read user experiences before buying.

When your CPU reaches and maintains 100% for extended periods, it's a sign you should reduce graphic settings or lock your frame rate until CPU usage stays below 100%. A good cooler that outperforms the standard one is essential to keep your CPU cool during those high-percentage moments. As long as your CPU remains adequately cooled and stays about ten degrees below its maximum temperature, you should be okay.

You should investigate Rust thoroughly. Check out videos of people with comparable specs to understand their experiences. If similar frame rates are becoming common, it's likely normal. Some games aren't optimized well, which can lead to unusual usage patterns.

If you need more than 100 fps even on the lowest settings, research the hardware that enables over 100 fps in the game you're playing.
