I think the way you have phrased these examples currently showcases your resilience and patience better than your drive and ambition. I'm not usually picky about examples and generally feel that any work as long as you're able to explain your thought process behind them and get them to fit what the question is asking, but my advice for this one is going to be a little different and more detailed.
Firstly, I'd say to introspect a bit on your experiences to find examples where you set a goal (ambition) and the way/ways you tried to succeed at it (drive). So if you take your second example, the way I'd phrase it to meet what the question is asking is by stating how you set a goal to achieve a certain grade (rather than to improve your grades) and how you went about this.
Secondly, structure would be really key here. Start off by stating your goal/ambition (getting an XYZ grade) ➡️ what motivated you to achieve this goal (wanting to do well academically for XYZ reason, you wanted to improve from previous year or improve your essay writing skills etc.)➡️ the steps you took to achieve this goal ➡️ any challenges you faced in doing so and how you overcame them ➡️ round off by stating the outcome of your efforts.
Does this make sense?
