"DSLR are dead" is a clickbait that is often used by several more sensationalist channels. They still sell far more bodies and lenses than mirrorless cameras. It is true that R&D budget is moving to mirrorless cameras, but that's mainly because the DSLR systems are very mature at this point.

They are still the cameras of choice for sports and wildlife when you use longer focal lengths and have erratic subject movement. They still offer far better battery life.

Mirrorless and DSLRs will move side by side for many years still.
