While what you calculated is correct, you don't take into account how chances work and especially how computer respectively software works.

While an added value on a percent value seems to be a bigger advantage for lower numbers, it actually can be less of an advantage. The main reason for this is that the calculation takes place every time on its own. If you do a calculation with a 95% chance 100 times, you won't get 95 successes and 5 fails. It's highly likely to result in 99 or 100 successes. On the other hand a 10% rate might fail every time.

So if you increase 20% to 30% you may still fail most of the time while an increase from 90% to 95% might increase your chance dramatically.
