Is uncertainity in goals with no way to turn back without consequences is worst?

Heyy I'm a final year student in b.e biomedical engineering kinda niche but has potential if we choose the right direction from it. I come from a very lower middle class family we live paycheck to paycheck. I love this course and my family supports me to do what I love so I took this program with no obligation. My collage is known for good placement but I later realised they show partiality openly i knew i wouldn't even get my fair chance in good companies that come for placement recruitment. 6 LPA is the highest they come to my college when it comes to core placements. I might get into one of 4 LPA ones fs. So I chose higher studies instead of placements probly try ireland I always wanted to do it and this course is kinda like a leverage for it as well.

But I took education loan for my UG so I have to pay back and also only my mom works so it's one income fam. Me and bro have to support in future when mom can't anymore. Now the problem is that I'm getting doubts about my own choices. Like i would have stayed here get to the top by climbing the ladder slowly, pay back the loan simply to put - playing safe.

Uncertainty is still there cause in india hardwork isn't the only thing that gets you to top

Here is the catch, if you are soo down the well beyond playing it safe you risk it all, I mean its managable for now so I have time to risk and get it together (hopefully) if things go wrong. But is it worth it?

I try to be calculative as much as I can. Such as just like how india is IT hub, ireland is known for its medical device manufacturing hub. Job market for this exist there.

Risk is there as much as payback is higher. I have plans and starting buisness in india after few years of experience I see the gap for it in india.

Even if I have to turn back to playing safe I have to find a job outside of college since I chose the latter,it's gonna be much lesser than my clg placement job but I probably can reach a stability after few years (hopefully they won't get me married before that lol)

But uncertainty..it's always coming back. Can you guys give me some suggestions ? Like what do you think of my situation? Is it worth the shot? Balance both experience and responsibilities?
