Maybe 50 microseconds, not 50 milliseconds. 1/1000th of what you assumed.
Towers are typically up to a few miles away in dense areas; they don't work well beyond 15-20 miles from the cell phone.
Waves go 186,000 miles (or 300,000 km) per second. Assuming a 10 miles distance from phone to station, it takes ~25 microseconds to do the trip, which is ~50 roundtrip.
So, in other words: latency is NOT affected by 5G much.

That's assuming latency is entirely due to propagation delay, in which case obviously a change in technology wouldn't help. Latency isn't entirely due to propagation delay though.
