How can I make a count of counters? Let's say there are two variables where the range from and to is set. And for example, every minute this number on the page will be updated within the range.

And you can somehow make the number by which the number is increased/decreased was not sharp. Let's say the range is 50 to 200 and first the random number is 75, and after one minute 200, so that plus or minus the previous value is for example 5, not such a big jump.
