Does everyone pay congestion?

I'm curious, does everyone really have to pay congestion charges when it comes to cryptocurrency transactions? I understand that traditional financial systems can often face congestion and delays, leading to additional fees. But with blockchain technology and its decentralized nature, shouldn't transactions be smoother and faster, without the need for congestion charges? Are there any specific instances or scenarios where congestion charges might still apply in the world of cryptocurrency? I'd love to gain a deeper understanding of how this works.
