thanks guys, yes the video is very clear but my question is, is there always going to be a way to get my bitcoins or send them from my paper wallet even in many years?
Yes, your paper wallet contains the private key which can be imported in almost all the wallets with the exception of a few and hence the coins stored in your paper wallet will always be spendable.
also I was reading somewhere that if you only send a portion of bitcoins stored on that address you end up loosing the remaining btc? for example let's say I have 10 bitcoins on that specific address of my paperwallet, and I send 1 btc to a different address then I loose the remaining 9 btc?
You could end up losing them is more appropriate to say which is why it is recommended to only use a paper wallet once but you can always send the rest of the coins to your OTHER paper wallet. For ex.
You have 10 Bitcoins on Paper wallet #1, you need to send 2 to Bob, so you send 2 to Bob and send the rest of it to Paper wallet #2, then they're again safe.
