Bad idea to aim for ambitious unis only?

I currently have a job. I have shortlisted 10 unis in Europe and Singapore but my counselor told me all of them are ambitious.

Unis: KTH, TU DELFT, EPFL, ETH, Twente, Eidenhoven, NTU, NUS, Imperial, UCL

My cgpa is 3.9/4
GRE: 309 (159Q, 150V) but 2 of the unis require GRE

II have a btech in CS and MBA in finance.
I am looking for masters in robotics or CS that has robotics elective.

I don't want to apply for other unis as I don't find them appealing enough to spend a huge amount of money to study. Might as well continue with my job and look for foreign opportunities. What do you think? I paid for Yocket so it doesn't make sense for me to go to 'target unis' after paying so much. I am doing all the research on courses, deadlines, requirements etc. I thought Yocket at least helps with that.
