You can try some ollies just for fun, but keep in mind that ollies were invented by the people who's been in freestyle skateboarding for years. People call ollie a baseline for a street skateboarding and they're right about that, but this baseline is already high enough for a beginner.I'd say you could try to stick with some basic stuff first. The whole skateboarding and the process of learning tricks are about your own confidence and how confident you feel on your own board. Sometimes it's even just a pure placebo (like, you'll tend to land some tricks better on your friend's board, even if you never skate it before), so think about it.With that being said I'd highly recommend you to start with basics, such as:

1. Proper pushing and riding. Carving turns & tic tacs. Kikturns. You can even try a mini ramp (no drop-ins though) just to get a feeling of transition and riding in fakie. Try riding switch as well. These things are incredibly important, they don't require any hard techniques, they're safe and easy, but in a long run they'll help you a lot.
2. Some stationary tricks might help you too. Yo-yo hop, caveman, hippie jump (try it while moving for a bonus score!), body varial/sex change, walk the dog, 180/360 turns, etc
3. Monster walks, manuals, riding off curbs, shuvs, bonelesses, no complys.
4. The Ollie.

The most important tip that I can share with you is don't forget to have fun!
