As a beginner, I bought Bitcoins few days ago when the price was $43,943 with the hope that since the price has been increasing rapidly, that it will continue to increase but now that the price is dipping I now found out that the Bitcoins in my wallet is also going down.
So my question is that can't it be possible for someone to buy bitcoins and hodl it at a specific price such that even if the price dips it won't affect the Bitcoins you have hodl in your wallet?
I don't see anything confusing in that and what you do not understand about how a price change works. You bought Bitcoin because you were expecting its price to increase so that you can earn profit which means you know that the value of your Bitcoins increases when its price increases, so what do you think would happen if the price drops? It's a simple thing, the amount of Bitcoins you have doesn't change but the value of your Bitcoins changes based on its price.
Consider Bitcoin like any other thing, maybe a product like a smartphone or a laptop. If a smartphone is priced at $1,000 today, and its market value changes the next month, that doesn't change anything in your mobile, but it will just change its market value which means that you won't get the same amount if you go for selling it back.
