What do you mean by "a healthy mindset"? It isn't healthy for society. It isn't healthy in the world where everyone has this mindset. It isn't healthy to treat your life as a lottery, hoping for a winning ticket instead of creating that ticket yourself. The fact that you consider applications to be uncertainties in life is very telling. You can make them much less uncertain, if you stop thinking of them like a lottery and start doing the things that prove you are valuable to others.
Did you know that USAMO qualifiers have >50% rate of admission to MIT? IMO gold medalists have >80% acceptance rate, and it's only so low because international admissions is limited to 10% of the student body. Life is only a lottery if you have an unhealthy mindset holding you back from improving yourself. Just because university admissions involve a lot of luck at the bottom does not mean you have to limit yourself to a bottom feeder spraying and praying to get in.
