The satellites are dwarfed by meteors. They won’t make a difference
44 tonnes of meteorite per day falls into the atmosphere! [1]
There are 8000 satellites in orbit (including dead ones). Seems like most are under 1 tonne. That's 8000 tonnes maximum so if it all comes down in 1 year (somehow), it's less than the mass of meteorites for that year.

Also, if Starship is successful as planned, means on average several tons launched per day, most of which mass to be deorbited just few years later. Starlink plans to deorbit thousands of satellites per year, V2 are 800kg already, likely getting heavier if launching gets cheaper.
