Your Flight has been ticketed electronically (e-Ticket).
Please take note of this important information:
:. Flight Details Your air reservation (PNR) number is: 12345678（※番号は置き換えています）

というものが送られてきたので、無事予約はとれているかと思ったのですが

:. Credit Card Authorization
NOTE: Your booking has been created and is pending credit card authorization from your credit card provider. We have generated this confirmation in order to confirm receipt of your booking. Please note, however, that your booking is still subject to cancellation unless payment is processed and successfully received. If your credit card is declined for any reason, and your booking is cancelled due to lack of payment, any payments received will be lost and you will be responsible for any rebooking fees as imposed by the supplier including possible price and itinerary changes.

:. Important, please read
Electronic Tickets (e-tickets) will be issued where possible. Certain airlines do not offer e-tickets on all reservations. If e-tickets cannot be issued for your reservation a paper ticket will be shipped to you. Additional fees will apply to all paper tickets. Please review our terms and conditions on the website for details. This fee covers shipping within the continental United States and the handling for your paper ticket. Additional charges will apply for other shipping destinations.
Passengers are required to reconfirm flights 72 (seventy two) hours prior to departure with the airline you are traveling with. Passengers are required to arrive at the gate 3 (three) hours before departure for international travel and 2 (two) hours prior to departure for domestic travel. We are not responsible or liable for flight changes made by the airline. If a passenger misses or does not show for their flight and does not notify the airline prior to missing or no showing the flight, the passenger assumes all responsibility for any change or cancel fee and/or possible loss of ticket value. This no show policy is an airline enforced rule and at their discretion to determine how they will deal with it. However, most airlines look at no shows as a violation of their ticket policies meaning you forfeit any and all funds paid for said ticket. Frequent Flyer Mileage can be accrued on some carriers. Please contact your airline to advise your mileage number. Fares are not guaranteed until ticketed.
Passengers are responsible for all of the required travel documents. If the passenger attempts to fly without proper documentation and are turned away from the airport or required to cancel or change their tickets because of lack of proper traveling documentation, then the passenger assumes full responsibility for any and all change or cancel fees if applicable and/or the loss of the tickets purchased.
As agreed when you purchased your airline tickets, all tickets sold are NON-REFUNDABLE.

これはもしかするとキャンセルされてしまうということでしょうか？

英語がまだそんなにできないもので…
翻訳やアドバイスなどいただけると幸いです。

聞いた事のないサイトなので信用性についてはわかりませんが、見る限りでは予約は通っていると思いますよ。

カード決済が通らなければ当然予約取り消しになりますが…。後の長い長い文章は注意書きです。72時間前に航空会社へ予約確認をしろだとか、チェックインは国際線で3時間前、国内線で2時間前にするようにとか、航空会社によるフライト事項変更の免責だとかですね。
