Differences between tire abbreviations (TCS , TLR , TR , TT ..)

Hello everyone , I just got into biking recently , and I'm kinda struggling to understand if a tire is ONLY tubeless , or it can be use tubeless and with tube or if it just tube only , I'm feeling kinda dumb.

I don't get it

Can someone be so kind to explain it to me ? thanks in advance !!!
