Am I suppose to achieve my "Goal" Calories?

Are you using a food scale to crunch the numbers? Use a scale for everything except liquids.

Here’s a thing about the calculators- the calculators are based on averages & statistics. But no one is exactly average. Think of the number MFP gives you as a starting point. Unfortunately the only way to find out a your actual calorie target is trial and error, a slow process that drives a lot of people to quit. Don’t quit. If you are using a food scale, keeping a food diary and are confident you have an accurate count, if you aren’t losing, try cutting 100 calories per day. Then see what happens. It’s all a big experiment. In fact the experimenting never ends because the calorie target that works for you now for have to be adjusted as you lose weight.

And this- weight loss has 2 parts, eating in a calorie deficit and living with it long enough for it to work. Avoid the temptation to go all in on the most aggressive deficit. People who do that generally don’t last long. You have to find a way to live your life while you are doing this. Good luck

With a physical job and some workouts, that's not an implausible weight loss calorie goal for someone your size/sex, though I'm guessing at your age when I say that.

If it is correct, and your logging is accurate, you're severely under-eating. Being a little under goal is OK, or even a lot under on a rare day. Being a lot under and doing that often is riding for a fall. What fall? Could be failing out because it's too hard, deprivation-triggered binges, weakness/fatigue, health compromises (some various severe ones a possible, though lower odds), loss of muscle alongside fat loss, hair loss, and more.

Under-eating isn't a good plan. Your buddy is semi-right in that regard. But it's not right that eating too few calories results in no weight loss. If that were true, no one would ever starve to death, or they'd be fat when it happened. Sadly, people worldwide die of starvation in numbers daily, and they aren't fat.

But it's definitely wrong that fewer calories is always better. Ultra-low calories is a trap. It's bad for reasons I mentioned above, and it's hard to stick with long enough to lose a meaningful total amount of weight because eventually our bodies fight back via fatigue/illness/hunger, then we overeat or give up. Dial in a reasonably moderate weight loss rate, and stick with it. For someone like you, at your current size, something in the 1 to 2 pounds a week loss rate is probably fine, with a little caution close to the 2 pounds since you have an active life so there's more fatigue/appetite risk at the faster end.

Eat close to the goal for 4-6 weeks, logging carefully. Then, if you don't lose weight, cut calories a bit and continue. That's the standard recommended practice.

The big prize on offer here isn't reaching goal weight, if you ask me. The big prize is reaching a healthy weight then staying there long term, ideally forever. Going to extremes during loss doesn't help a person experiment, find and practice the new, permanent eating/activity habits they can continue forever to stay at a healthy weight. "Find positive new permanent habits" is a different mindset from "lose weight fast (then go back to normal". Give it some thought.

(My "credentials"? Lost from class 1 obese to a healthy weight nearly 10 years ago, stayed at a healthy weight since. The quality of life improvement has been huge, more than worth the effort. Lietchi and 88Olds who replied above are regular MFPers I know who have lost a bunch of weight and kept it off, too. I'm not dissing other replies from people I'm unfamilar with, but I know those two give solid advice.)

Best wishes!
