how do i deal with caro kann and sicillian

Against the Sicilian, I propose this original idea, which is quite unknown to the general public. There are no books about it.
Against caro kann an original idea too :

Play the advance caro with 3. e5, if Bf5 you go 4. h4 for the tal, and if h5 5. Bg5!? is a good line to catch unprepared opponents with. they don't have to go for 5. h5 though, h6 and Qb6 are alternatives which you should also study. Against 3. c5 from black instead of Bf5, you go 4. dxc5 with 5. f4 vs Nc6 and 5. a3 vs e6
Vs. the Sicilian, at least for your level, the Alapin could be good but I personally think that the Open sicilian is better. If you aren't too worried about changing openings later at a higher level and just want some quick wins now, Gambits like the smith morra, mangarini or wing gambit coudl work too. I will add diagrams to help you too.
All of this will require further study as you go higher up, but as a simple enough solution for now play these. Enjoy!
(I use the advance vs. Caro myself, and it works great)

I can't speak to the Sicilian. I'm mostly a 1.d4 player as white so don't see it played against me too often. But Caro Kann is my bread and butter as black. I can't imagine many people under 1000 go super deep into theory (maybe I'm wrong). The point is, you want to choose a testing line for black. You're basically telling them, "Okay, you want to play this opening against me. I'm going to make you prove you know what you are doing".
I'd recommend going with the Fantasy. After 1.e4 c6 2.d4 d5 you are going to play f3. The point of f3 is that many players will respond with dxe4 and then you can retake with the f pawn. You end up controlling the center, black is cramped. If they play Nf6, you just push e5 and chase them away. Then you develop your pieces, castle king side, and have yourself a chill game with major space advantage.

Know Thyself. You have a variety of options against both. For example in the C-K 1) You like near-symmetrical positions in which to manoeuvre, there's the Exchange Variation. 2) You play 1. d4 as well as 1. e4 openings and do well with asymmetric IQP-ish positions, there's the Panov-Botvinnik Attack. 3) You like a locked centre and a super-sharp game in which you must keep the initiative, there's the Advance. 4) You like both complex open positions and strategic open positions with more space, there's the Classical 3. Nd2 4. Nxe4 approach. 5) You like to gambit, there's 1. e4, c6; 2. d4, d5; 3. Nc3, de; 4. Bc4. 6) You like a complex mess, there's the Fantasy Variation. And so on.
they literally kinda annoy me when someone plays this instead kings pawn opening
