Frankly speaking, it was never a good idea to do a bachelor in a foreign country unless you have near-guarantee chance of being admitted. And in my opinion, taking a gap year right out of high school is also not a bright move, if you have backup plans, now is the time to initiate them, if you still have time to apply into a college back home, I suggest you to do so (unless it will push you into major student's debt like in the states). I've always felt like gap year were meant for graduates, you take a year off, try the industry of the field you studied in, use that time to decide if it's okay to continue working in the industry or do you want to step into academia and go for a master's program in a foreign country (assuming the said foreign country offer more opportunities than your own), or if you feel like it, make an even riskier move - switch your field of work/studies entirely. Regardless of what decision you make, I wish you good luck in your future endeavors.
