Hey aspirant, your expected marks in Gate 2019 are quite low. With these much marks, you will only be able to clear the cutoff(my prediction is based on the previous year cutoffs).

If we refer to the previous year gate cutoffs then it's clear that your score is not at all good enough for getting admission for M.tech in any of the good NITs and you hardly have IITs available as an option.

I will suggest you calculate your expected gate score using the score predictors available as it will be easier to look for colleges on the basis of your gate score. Click on the link below if you haven't calculated it:
