When you have good luck or a good situation, but you try too hard to extend it or get an even better situation, and risk having a negative result or losing what you have achieved so far.
When you are unable to have what you want.
This phrase means something is completely by chance or random; you cannot control it at all (similar to winning the lottery, when they "draw" - take - the winning ticket completely at random).
When a situation did not have the positive result you hoped for.
An unfortunate state resulting from unfavorable outcomes.
Say these when you want to wish/desire someone good luck, good results; you hope they will succeed.
When a new or inexperienced person has a great success, you can say this expression – the success happened by chance, not because of the person's skill.
